Simply looking for approval on the build, and what I can improve on it

Fine. I approve. Should I take a look at your home loan too? Nice thread.

I am adding two 500 GB Bare drives for a RAID setup as well. These drives will take advantage of the 6 Gb/s Connectors on the Motherboard.


You'll need more drives to see any benefit from SATA III speeds.....WD reports the speed of the drive at 126 MB/s. 126 x 2 is not going to break the SATA II barrier....so SATA III not doing anything for ya

And RAID is not going to help you gain fps. Don't get me wrong, RAID helps in a fair amount of applications, gaming just isn't one of them. I'd invest in an SSD before I'd invest in mechanical drives in RAID. Here's the ole RAID schpeil.....haven't checked the links in a while and some of the data related to controllers I'm sure is outdated.

Western Digital's Raptors in RAID-0: Are two drives better than one?

"If you haven't gotten the hint by now, we'll spell it out for you: there is no place, and no need for a RAID-0 array on a desktop computer. The real world performance increases are negligible at best and the reduction in reliability, thanks to a halving of the mean time between failure, makes RAID-0 far from worth it on the desktop."

".....we did not see an increase in FPS through its use. Load times for levels and games was significantly reduced utilizing the Raid controller and array. As we stated we do not expect that the majority of gamers are willing to purchase greater than 4 drives and a controller for this kind of setup. While onboard Raid is an option available to many users you should be aware that using onboard Raid will mean the consumption of CPU time for this task and thus a reduction in performance that may actually lead to worse FPS. An add-on controller will always be the best option until they integrate discreet Raid controllers with their own memory into consumer level motherboards."

However, many have tried to justify/overlook those shortcomings by simply saying "It's faster." Anyone who does this is wrong, wasting their money, and buying into hype. Nothing more.

http://computer-drives-storage.suite101.com/article.cfm...
The real-world performance benefits possible in a single-user PC situation is not a given for most people, because the benefits rely on multiple independent, simultaneous requests. One person running most desktop applications may not see a big payback in performance because they are not written to do asynchronous I/O to disks. Understanding this can help avoid disappointment.

http://www.scs-myung.com/v2/index.php?view=article&id=7...
What about performance? This, we suspect, is the primary reason why so many users doggedly pursue the RAID 0 "holy grail." This inevitably leads to dissapointment by those that notice little or no performance gain.....As stated above, first person shooters rarely benefit from RAID 0.__ Frame rates will almost certainly not improve, as they are determined by your video card and processor above all else. In fact, theoretically your FPS frame rate may decrease, since many low-cost RAID controllers (anything made by Highpoint at the time of this writing, and most cards from Promise) implement RAID in software, so the process of splitting and combining data across your drives is done by your CPU, which could better be utilized by your game. That said, the CPU overhead of RAID0 is minimal on high-performance processors.

Even the HD manufacturers limit RAID's advantages to very specific applications and non of them involves gaming:

Run ya system through a good PSU calculator before risking ya new card to the PSU ....if it's an olde rone where capacitor aging may be an issue, I'd be wary.

...Moving on, My main concern is really if a 600 Watt power supply will actually work with two 6850s along with the possibility of over clocking.

EDIT:

The RAID is more or less for recording at higher resolutions with FRAPS and my Capture Card. The SSD seems tempting, a little small, but I suppose that is why I already have a 1 TB Caviar Black for Storage.

I had originally tried for two 460s, but the problem is that it requires more power connections, meaning I would need another power supply, which you didn't include in the final price. I'll have to look into options for that, but with a good power supply it may be slightly over budget, seeing as your total is already up to 1,028

I would throw that PSU at some kittens before I would use it in a build.

My first part of the previous post was directed at the person who decided to make a crack about a home loan rather than give any help at all, after posting, I had to quickly edit my post to reply to the one that was posted while I was replying to the other one. I don't see how I am disregarding any help being provided, and saying you would throw my PSU choice at kittens before using it in a build obviously means you think it is a bad power supply, but you didn't give me any reason why. I'm curious as to what is the problem with the power supply.

To Jack Naylor, I used that site for calculating wattage, but I can't find any Sandy Bridge models on the processor selection.

EDIT: Just re-made the price at the top to be with a 750W PSU and two GTX 460s. The price is also after rebate, and I also threw in the Spinpoint and SSD that was suggested. I picked the power supply out of reading the thread that was linked, so I think it will work nicely.

Just choose an i7-860/870 ,for the calculator, which have the same tdp rating and core/thread count. But with an i7-2600k and dual 6850's a 650 watt will be enough

edit: woops i thought u'd picked the i7, if you have the new i5 then put the i5-760 into the calc for the same reasons stated above.

Okay I'm not exactly following and unlike the trools in this thread actually do want to help you. What PSU are you planning on using? the corsair AX750 or some 600w which I'm not aware of.

for dual 6850s a 650w will do fine and leave overclocking headroom I recommend the ea650w http://www.newegg.com/Product/Product.aspx?Item=N82E168... 65 dollars

I decided to go for Jacks advice and try a GTX 460 SLI build, and decided to upgrade to the corsair 750W power supply. I may be able to go for a smaller PSU according to the Antec Wattage calculator, but I don't have enough PCI E 6 pin connectors for two GTX 460s. The Corsair I added comes with 4x 6+2 pin connectors which is enough to power the cards.

Well you can use the little connector majiggs that come with the cards and run it off of the ea650, a member of these forums was running 2 470s off this psu with no problems (that isn't advised though 470s are much more power hungry)

I use the extreme psu calculator it's very accurate http://extreme.outervision.com/psucalculatorlite.jsp

If you must go for a psu which will support your cards without adapters use the xfx 750w it is a great quality psu and is much cheaper than the corsair http://www.newegg.com/Product/Product.aspx?Item=N82E168...

I read the ...moving on before you edited it replying to jack's message. I thought you were moving on from his reply, but I realize u were 'moving on' from the karate kid jackass.

Here is why I would change PSU: While I believe (it's been a while since I looked @ it) the Everest Group 600w is a 80 plus certified PSU, I am a big believer in never skimping on a PSU in a system. You are planning on putting some nice components in your rig, give yourself the peace of mind of using a quality 80+ bronze or better PSU by someone like Antec or Corsair. Also, getting something maybe in the 750w range will allow SLI/Xfire as a future possibility.

But I also think that you will be much happier with a SSD boot drive for your OS and maybe your most frequently played games (and the 1tb storage) than a RAID array of mechanical drives.

Sorry, you just wouldn't believe the # of ppl that come here and then get impatient when people are trying to help, and I realize this isn't the case for you. I will edit this in the morning with more specifics about what I would do in your position!

Good luck!
