Hi guys. I'm in the process of building a new p55 (maybe x58) system and I'd like some input.

APPROXIMATE PURCHASE DATE:
Next Couple Weeks

BUDGET RANGE:
Roughly $1000 for remaining components

SYSTEM USAGE FROM MOST TO LEAST IMPORTANT:
Gaming (TF2, COD WaW2, crysis)
Web Browsing
Some Photoshop

PARTS NOT REQUIRED:
keyboard/mouse
monitor
vid card
case

PREFERRED WEBSITE(S) FOR PARTS:
newegg.ca
ncix.com
canadacomputers.com

PARTS PREFERENCES:
i5 750
i7 860

p55a-ud4p
p7p55d-e pro

i7 920
p6t

OVERCLOCKING:
I'd like to have the option available

Crossfire
I'd like to have the option available

MONITOR RESOLUTION:
1680x1050

ADDITIONAL COMMENTS/QUESTIONS:
I'm going to be in New York in mid February so I'm waiting to buy the cpu at a Microcenter. That said, the price of an i7 920 there is less than the price of an i5 750 here. Would it be wise to go with an x58 build instead? Or stick with p55 and go with an i7 860?

If I do decide to go x58, is the p6t a good option for a mobo?

I like the idea of p55 because I've heard it runs cooler and more efficiently than x58.

Would a corsair 650TX be sufficient to power a p55 rig with two crossfired 5850's?


I have already purchased an Antec Three Hundred Case and an HIS 5850 video card.

You picked a bad case to want to Crossfire with. In addition, Crossfired 5850s is completely overkill for your resolution. In fact, one 5850 is overkill...

Here's what I would get (using Newegg prices):

CPU: i7-860 $280
Mobo: Asus P7P55D-E Pro $190
RAM: Corsair XMS 3 1600 mhz CAS Latency 7 $110
HDD: Samsung Spinpoint F3 1 TB $90
PSU: SeaSonic 850W 80 Plus Silver $110
Optical: Cheapest SATA DVD burner $25

Total: $805. Possibly tack on a small SSD for the boot drive.

I choose the 860 because it'll be the same performance for less. In addition, the benefit of the full 16/16x lanes on the X58 translates to a 4% performance increase for about $200 price increase.

The PSU I choose is excellent, and will be overkill even if you crossfire. I highly suggest getting a smaller one if you decide not to try to Crossfire. A 750W should be enough.

Can pick up an i5-750 $180 or i7-860 $220 at microcenter as well. Don't bother with x58.

P55 vs x58 summary I've been posting

Don' t know why ppl have such a hardon over the i7-920. It is worse at gaming than an i5. Worse at everything vs an i7-860.
http://www.tomshardware.com/reviews/quad-core-cpu,2499-...
http://www.anandtech.com/cpuchipsets/showdoc.aspx?i=363...

It's 4% FPS increase w/ xfire due to dual x16in gaming is negated the 860's better performance, or completely negated by using a 5970.
http://www.anandtech.com/cpuchipsets/showdoc.aspx?i=364...

i7-920 only ties a Phenom II x4, half it's price, even with a 5970.
http://www.legionhardware.com/document.php?id=869&p=23

i7-920 has horrible minimum frame rates. Worse than even Core 2 Duo and Quads in some games. P55 CPU's and AMD Phenom II's don't.

http://www.anandtech.com/cpuchipsets/showdoc.aspx?i=363...

Triple Channel offers no difference at worse, a only discernible in benchmarks difference at best.

P55 chips use less power and run cooler than x58.
http://www.tomshardware.com/reviews/intel-core-i5,2410-...

The only advantage of the i7-920 is that you can upgrade to an i9 later this year. The questions is, after buying a i7-920 for nearly $300, do you really want to upgrade to a estimated $600 chip within the year?

If not, both x58 and P55 will be outdated in a year when 22nm sockets come out.

I have an i7-920 system and an i5-750 system. The i7 was great when I built it a year ago. Currently, I see absolutely no reason to go with x58.

Technically a 650TX will run 2 5850's, but doesn't have enough 6pin connectors so you'll need a molex to 6pin adapter cable.

Also as MAD said, don't need xfire 5850's at that resolution. In fact, outside crysis only 2560x1600 would benefit from a second 5850.

Stick with the seasonic PSU. A 750tx is the same price so might as well get the seasonic.

Thanks for the great advice.

Is the Three Hundred bad for crossfire because of size or heat?

Why do you recommend the p7p55d-e pro over the p55a-ud4p ? Seems like a lot of reviewers on newegg are complaining about a high pitch noise emanating from this board.


Also, if the 5850 is overkill for that res, should I totally forget the idea of crossfiring and go with a cheaper board. ie p55a-ud3?

Case: Kind of both. They go hand in hand. The 300 is a great case, but generally only recommended for the cheaper builds.

Mobo: I've heard that a couple of times. I'm not sure what to think of it. However, I recommend the Asus because the Gigabyte has "fake" USB 3/SATA III. If you were to Crossfire, those ports only operate at normal speeds. With the Asus, you spend only $5 more and get full functionality.

GPU: That depends. If you never upgrade your monitor, you should be alright with a cheaper, 1 PCIe slot board. If you do replace it (or add more for Eyefinity), eventually the 5850 will not offer high performance. Frankly, the number of people who Crossfire is very low. I don't particularly see the value with the higher end cards.

One more question for you guys. I'm probably going to buy today from my local Canada Computers shop.

What ram would you recommend from this site where it is available in Waterloo?

I don't fully understand memory timing. Those ripjaws are 7-8-7-24. Is that decent?

Yes they actually nice timings for 1600 memory. Most on average are around 8 or event 9.

That's great. Unless you really need to keep costs down, CL 7 is what you're looking for. It's more important than the speed of the sticks.

What are your thoughts on this psu.

Antec EA-750 EarthWatts 750W.

It's the cheapest 750w psu at Canada Computers.

Ok, I have said this many times and it is a bit of information I like to share. When building a computer the PSU should not be the last thought or the cheapest one. The one you have the reviews seem to be alright but I do not know much about it. With a PSU it should be an investment do not be afraid to spend extra on it, it is what powers your system, cheap ones can cause components to fry.

Just a tip when looking for a PSU don't try to go cheap try to go for a good brand and trusted product that won't cause issues later.

Second what hopkiller said. However, Antec Earthwatts are very realiable PSUs that are often priced farily low. It's an excellent choice to save some money and get a quality unit.

OK guys,

I'm heading to the store in a couple hours. Just wanted to get some final thoughts on my component selection. These prices are from Canada Computers in Canadian dollars (obviously).

i5 750........................................................$224.99
or
i7 860........................................................$319.99

Gigabyte GA-P55A-UD4P................................$190.99
G.Skill Ripjaws - DDR3 1600MHz 4GB................$127.99
Antec 750 EarthWatts...................................$110.00
Western Digital Caviar Black 500GB..................$65.00
Antec Three Hundred Case.............................(already purchased)
HIS Radeon 5850..........................................(already purchased)


Note:
Canada Computers doesn't have the p7p55d-e pro, so i figure the ud4p will limit me to two upgrade paths. either crossfire OR usb3 components. I've read that this board works well for oc'ing. Thoughts?

The i7 860 is quite expensive at CC, but I really don't want to wait two more weeks to be near a Micro Center.

Please let me know what you think.

The board is a good substitute. Just don't forget you don't get both.

Is the Samsung Spinpoint F3 500 GB not available? It's faster than the WD. If it isn't, get a Seagate 7200.12. It's still better than the WD, but not as good as the Samsung.

Don't you get like $50 off Intel CPUs at Microcenter? I'd just hold off on ordering everything for a week or so, buy the CPU at Microcenter, and then everything will be there at about the same time.

If I go with the 860, I'd save $70 if I buy at Microcenter. But I'm impatient. The 5850 just sitting there is killing me lol.

True. The service at Canada Computers is effing terrible anyway. Makes me not want to support them. I guess I can hold off a couple weeks. :) 

Thanks again for all the help Admiral.

To be honest I would order from the Canadian Newegg. Dude newegg is great at getting components to you really quickly.

Core i7 860 at newegg is $305 Canadian dollars, no tax.

Got the system up and running! :D 

Here's what I decided on:

p55a-ud4p

i7 860

ripjaws DDR3 1600 (7 8 7 24)

spinpoint f3 - 500gb (probably double this up in RAID 0 or add an ssd in the near future)

HIS 5850

cooler master hyper 212+

antec 300



It's up and running smoothly, but I was hoping you guys could answer a couple questions for me.

1. CPUZ reports my DRAM frequency as 683.5 Mhz - Is there something I should do to get the clock to where they are rated?

2. I'm getting the 'big cursor' issue. I plan on updating my bios, hopefully that solves the problem. Any thoughts?


Thanks!
