I7 975 w/ HD Projector Build

Last response: in Systems

Projector is: http://www.testseek.com/home_electronics/video/projecto...

My budget for the computer itself was 3k, as much as the projector cost (w/ equipment) but the projector of course is also to impress women who don't care how nifty a rig I have.

Intel i7 975
Asus P6X58D Premium (option to upgrade to Gulfstream)
6gb Corsair 2000mhz
Seagate Cheetah 15k.7 300 gb Sata 3 6gb/s Hard drive
(I really wanted a OCZ Z-Drive, or at least a Sata3 SSD, but could not afford them . . . next year. . )
Cooler Master Cosmos S chassis
Cooler Master V10 CPU fan
Cooler Master 600w Silent Pro Power Supply
Logitech diNovo keyboard
Razer Mamba mouse (and gaming mouse pad, cause I'm a tool and a bit of a jerk)
Onkyo SKS HT540 7.1 surround system
And as soon as it comes out: nVidia GeForce GTX 480 video card (option to nab another one next year)

The idea of course was so I could play Mass Effect 2 and Fallout 3: New Vegas in the way that little baby Jesus wants me to, and that is on a 135 inch screen, at the highest resolution, with the most effects, the hi rez texture packs modders have out there, all the AA money can buy while sitting on my reclining leather couch. Of course I'll have to put aluminum foil over the windows, but I think it'll be worth it. I try to rationalize 6k for the whole set up as . . . some people pay 6k for a flat screen tv that still won't look as good as what I've got ordered.



So now questions:
Watercooling? Never done it before, might try it b/c I want to keep the temps under 60C at all times and still keep the thing quiet.
Overclocking? Never done it either. Don't think I really should need to, but really. . . why the hell not?
SLI? Yeah. Right. 700 bucks a card, I'll do that when the one shows its age.
OCZ Z-Drive? the PCIe 2.0 SSD reads twice as fast as a SATA III SSD, which reads twice as fast as my 15k.7 SATA III. I rationalized not getting it b/c it'll take my projector bulb longer to warm up with the HD I've got.
Blu-Ray? Is there an Sata3 Blu-Ray drive out there? I have a player coming too . . . but I figure I should make the most out of my SATA III.
Raid 0? Never done this one either. Is it worth it? The Cheetah is a buck a gig.

First, the 600W will be a little low for a GTX 480. Go for the Corsair TX750.

Second, why spend $1,000 on an i7 975 when you can spend $300 on an i7 930 which can EASILY be overclocked to the point of greatly surpassing the i7 975?

Third, don't buy a Velociraptor or Cheetah. Get either an SSD or a WD Caviar Black 2TB which holds a TON and is just about as face at even less the price. Gaming and HD video really don't need anything more than a normal drive.

Fourth, there are no Blu-Ray SATA III Drives out there, nor is there any need to be. Being that Optical Disk Drives only transfer at best a few megabytes every second, they can't even come close to maxing out even the old IDE ATA100 Interface. SATA III is completely pointless on an ODD.

Lastly, don't spend so much on 2 GHz RAM. It makes very very little difference to the point you won't notice it, and the CAS Timings matter even more. Save some money and get some good DDR3 1600 MHz or 1333 MHz with a CAS Latency of 7 or lower.

All that should up your budget a big and give you money for bigger and badder graphics cards, like a 3-way 5870 Crossfire setup.

600w a little low, or too low? It's already been ordered.
For the i7 975 I'm actually not spending a grand on it, it's a used one my buddy sold me for the gulfstream he's getting. Good deal on it.

The SSDs I looked at were great except they were all SATA II, or the few that were SATA III were not cost effective. The Cheetah was a judgement call really, I'm still planning on getting SSDs in the future.

ODD: That explains why the DVD drive I got that claimed to be SATA III was not prohibitively expensive. . . I should have known that.

The Ram is also used, but in like new condition, and is costing me less than 1600 Mhz RAM.

I really like the 480 tech, future-thinking features, tessellation, and always the option to SLI up to 3 ways on the mobo with 3x PCIe 2.0 slots

More likely than not over the next two years, one's getting another 480, the other's getting a Z-drive.

850 needed (at least) for twin 4xx series cards.

930 will overclock past a 975, but 975's can be OC'd to....and past 930's.

RAID 0 - unless you have an application where the vendor is saying you will reap benefits (movie editing, rendering, large databases) you won't see much improvement.

Vertx 2 drive, the new performance champ are expected this month.

An air cooler will do 4 GHz e-z on a 920/930 ....where you plan to go that you need WC ?

The optimal viewing distance (your butt to picture) is 33.75 feet for a 135" screen

Thank you both for input!

AC is fine, but if WC is quieter it's something to think about. I know people who've done it, assumed there was a reason for it.

The optimal viewing distance for an LCD TV may be that far away, but according to:
http://carltonbale.com/1080p-does-matter I only need 10ft. http://www.projectorcentral.com/Panasonic-PT-AE4000U-pr... recommends 14-22ft, but the first article makes a good point about being able to see the improvement of 1080p.

I'm not familiar with CAS timings or latency, what are they? What's important about them?

The MHz is the number of I/O Operations per second the RAM can do. The latencies are the number of clock cycles it takes for the RAM to respond to a data request from the CPU.

For 1,600,000,000 operations per second, and 7 clock cycles to wait, the CPU theoretically has to wait 4.375 nano-seconds (billionths of a second) to get data from the RAM. If you had RAM at 2 GHz but a latency of 14 clock cycles, the CPU would have to wait around 7 nano-seconds for a piece of data from the RAM, thus being slower despite the higher clock speed. However, after it begins responding the 2 GHz RAM will begin to catch up as they are both transfering data only the 2 GHz RAM is doing it more slowly. Thus it was slower to react, but faster to transfer data.

That being said, most RAM transfers are a few bytes or KBytes each, so in this case the 1600 MHz RAM wins by a long shot.

Think of it this way, the RAM Speed in Mhz is like the Sequential transfer rate on a Hard Drive. The CAS Latencies are basically like the access time on a hard drive.



An Example:

Drive 1 has an access time of 20 ms, and transfers at a max of 200 MB/s.
Drive 2 has an access time of 10 ms, and transfers at a max of 150 MB/s.

As such, for large sequential transfer operations where it only has to seek once, only 10 ms is wasted on drive 1 and then quickly made up by the extra 50 MB/s of thoroughput. Drive 1 wins.

For small, random read and writes, like an OS Drive, Drive 1 will lose by a long shot since the drive has to seek many many times per second, and much more time is wasted. Since Drive 2 seeks twice as fast, half as much time seeking is wasted, and it transfers data more quickly.

Hope that helped. :)

Yeap, much thank you! The 6Gb I have now I got a deal on like I said, but when it comes time to upgrade I'll grab 12 of the 16k, combined it'll probably be cheaper than another 6 of the 2k.

I'm debating whether or not to wait until April for that GTX 480, though I love the idea of it, I might see if I can find a cheap card to tide me over until then if only to watch movies with. Since this is a pretty elaborate system I'm gonna post pictures as parts of it flow in for posterity's sake. The rig's actually going to go in my kitchen pantry, being closest to where I'm hanging the projector. The Screen is going to hang in the middle of the living room (being more than 10 feet wide it would hit the fireplace if I put it further back) as this is the only place in my apartment to get the requisite throw distance for the projector. The speakers are going on the wall, the subwoofer will probably go in the pantry as well as the blu-ray drive. Couch is going where the kitchen table should be, and vice versa. I'll have the only apartment with a kitchen table between two end tables in the state. (not enough room for them where the couch is going to go.

Worth getting? Apparently the Cooler Master V10 is a 200W cooling unit since it uses TEC and 3 fans. I don't know if that means it's going to effectively leave me with 400w for my system, or 800w if I go with above, and if so the above is looking much more attractive.

I think I'm going to try this: it answers my earlier WC question, so long as I can find a good after market AC for the GPUs.

Though I have a property exam in four hours, I can't stop obsessing over my rig, can't sleep, and just keep reading articles. I missed out on the whole 5Ghz project in the end of 2003 with LN2. 6-7 years later to do the same thing with air? How can I not?

After copious amounts of research, leading me to believe the GTX 480 is only better at tessellation and tends to suffer post 8x AA, I decided to go with ATI for the very first time. Perhaps a little bit of that was due to impatience as well.

The Asus model coming out in a few weeks seemed to outperform all other 5970s out there, and the price of them varied from almost $900 on amazon, $700 on new egg, and $635 on onsale.com with free shipping. I have express warranties from them, otherwise I'd be suspicious of the price difference.

I also went with the Corsair PSU, being as one reviewer decided it was orgasmic in some way.

Thanks for the tip.

I emailed CoolIt about their new Omni universal water cooler http://www.coolitsystems.com/index.php/omni.html to see what price and time frame they can offer. The only other option on the market right now is a full WC system, or as one poster attempted, two AC units- one per CPU, but he did not say whether or not he was successful.

A full system would entail a pump, reservoir, radiator, block, backplate (optional), all the fittings, screws, hoses and such separate, and would not be cheap. I will consider either, as having such a large screen any flaw in the picture will be rather glaring, and as previously mentioned I want the best without an unlimited budget. Having received such a good deal on the processor and Ram, paying retail for the VC and whatever cooling system it takes to overclock (or at least undo the underclocking) does not seem ridiculously unreasonable.

So anyone who's been on ebay knows I lied about the processor and RAM coming from a friend. I'm happy about the price I got on the RAM and didn't want to shell out the 800 for the CPU. Looking at a recent Tom's hardware article about Bad Company, games that are quad-core enabled don't work each core very hard, even at very high resolutions, and at very high resolutions, there only shows a difference in about 1-2 FPS when overclocking from stock. So I'm thinking a $500-600 i7 950 will provide just as good an experience on games for the next 3-5 years or so.

Do any of you with more hardware experience/technical knowledge of the subject find that to be an accurate statement?



In other news, the screen and projector mount have arrived, as have everything but the PSU, CPU obviously, and graphics card. Very happy with the lot of it so far.

Honestly the only reason I looked at this thread was because it said something about an HD projector, and I had always wondered was pc gaming would be like on a projector. Well there goes five minutes of my life wasted. Good suggestions by the way.

If you want to close it down fine, I lied because I didn't want to advertise the deal I looked forward to on ebay, which was a great deal until the last hour of bidding (I should have seen that coming). It wound up going for as much as most new 975s never taken out of the box. Perhaps it was more offensive than I intended, and I apologize if it was, but it seemed a practical solution to me. I also posted about the PSU and the VGA and neither of those initial choices are the same, I only ever mentioned the 975 being from a friend because the decision was challenged over the price (and very rightly so).

Everything's here except for the projector (ships on the 12th), the CPU (another ebay bid, on a 950, ends in 12 hours), and the VGA, expected from onsale.com to ship by end of the month. The screen of the projector is here, the case, mobo, all the rest of it. I still do intend to show that projector gaming can provide a better experience than gaming on a TV, and that was the focus of the thread to begin with, with a few issues about the rig to iron out first. Namely, best combination for the money, above the budget end, below the highest end, all the money it takes for the best performance, without wasting money on parts that won't. I think it might still have some value there for anyone with the same mind frame.

If I am indeed morally blameworthy, I continue the trend by blaming it on Mass Effect for not teaching me values good.

Agreed.

I guarantee you won't notice any extra gaming performance by getting the 950 over the 930. Spend the $295 on the 930, do a very modest overclock, and then you will have a processor that performs on the same level if not better, and for less money.

In all honesty, there really is no reason to get anything more expensive than the 930 right now...

I look at it as a range, if I'm in the 300 range I want the best I can get in that range. I went to the 600 range for the 975, which I probably shouldn't have, but I wasn't as educated then. Not that I am now, just a little moreso than I was a few days ago.

March 10, 2010 7:31:01 PM

Lol no. Games (especially crysis) are SO video card intensive, that you would probably hardly notice any difference if you were running it on an AMD Phenom II X4 965 or an i5-750 versus an i7-930. Processing speed only carries you so far in gaming performance...

The processing speed will only really shine if you are doing very processor intensive tasks such as video encoding.

So what i'm trying to say is that you MIGHT be able to overclock a 950 higher than a 930, but that small bit of speed will show no difference in games.

I would not go to 4 GHz either. I would go with something that doesn't draw so much power, more around 3.6 GHz. That should be a sweet spot for playing games, and it's considered a fairly modest OC. This should help keep your system cooler and last longer.

It's not going to make enough of a difference in the fps you see to justify the price differential.

Most games these days are GPU-limited. THG recently had a couple of articles about building a balanced PC, while they certainly show some CPU-bottlenecks, it's mostly with older CPUs. GTA4 was one of the few games that really benefited from a more powerful processor.

Since this is a homebuilt forum, a lot of the emphasis is on value, rather than absolute performance. People frequently say "best" when what they really mean is "best value" or "best value in that price range".

Now, if you want the fastest processor for bragging rights or whatever, sure, go for the i7-975 or whatever crazy processor you want. But it's hardly going to provide enough real-world benefit compared to a $200-$300 processor for most people with normal-person budgets.

For real-world gaming performance, most of your money should go to the graphics card. No modern processor should bottleneck even the fastest graphics card.

As long as you spend your money wisely on quality components and don't overbuild portions of the computer that don't directly affect your intended usage (like getting 16 GB of RAM for gaming or something), then you'll be fine.

Haha well it is still taught via advertising that clock speed is always the most important. That is definitely no longer true. For most people, 2.2-2.4 GHz is fine for all of their everyday tasks. However they all believe that they need to get the faster processors when all they are doing is surfing the web...

It's the same with games, just on a different level. Processors only bring so much to the table. Save the money and put it towards either a faster (or second) video card, or get a nice big ssd. There are so many other places you could put the saved money and you could actually ENJOY the money you spend.

Man, that's. Still crazy. I know SSDs are the big rage these days, but isn't everything still limited by the sata transfer rate? Excepting the z-cards of course. And does that affect the gaming or just the loading? Mass effect 2 runs fine on my laptop, but I once had to wait 5 minutes for the ship to load. Worse than the witcher . . .

Well sure, but the point is not that SSD is going to be a HUGE leap over a regular HDD, but that it is a much better leap than getting a more expensive processor.

An ssd will decrease loading times, and will help your system boot up faster as well as speed up the time it takes to open applications. It will make your system feel snappier overall.
