APPROXIMATE PURCHASE DATE: Today BUDGET RANGE: 1200, after rebates, taxes, shipping (90042)


PARTS NOT REQUIRED: Keyboard, mouse, speakers, graphics card (have an XFX 5850)

PREFERRED WEBSITE(S) FOR PARTS: Newegg, amazon, microcenter (Orange County)

PARTS PREFERENCES: by brand or type: Intel

OVERCLOCKING No SLI OR CROSSFIRE: Yes, hope to go to 2x5850



1. Are these the same?

If not, is the Newegg better enough that I should spend the extra $10 for it (shipping and taxes)

1b. Is 750w enough for 2 5850s and the below build? Might I be able to drop to 650w to save on energy costs?

2. I am most worried about the motherboard given the "crackling/whining" issue some people are having and wondering if I should get GIGABYTE GA-P55-UD4P LGA 1156 Intel P55 ATX Intel Motherboard ( ) instead. I know the gigabyte does not have USB3 and such, but I figure I could also get a PCI card to do that if I ever need the feature?

3. Is the below build good? How might you improve it?

4. Could someone tell me how I might make sure the ram is going to be compatible with this build or with the gigabyte? Not sure what websites are good for this these days.

Thanks everyone!

Switch the hard drive for a Seagate 7200.12 or Samsung F3 as they are faster and quieter then the WD drives for now.

You build seems to be perfect except for the HDD. Good build.

Oh yeah, the i5 750 should be enough for two 5850's ;)

Both PSU's are exactly the same and powerful enough to run your setup and a lot more! However you will need to buy two 12V molex to PCI-e converter cables as the Corsair only has two PCi-e and each 5850 needs two.

1. Yes they are the same. That said, you should get the non-modular version to save some money. The HAF is a bottom mounted case, so the extra cables will sit below the motherboard, keeping them out of the way. What do you mean extra $10 from Newegg? It's the same price, free shipping, and has a $10 rebate.

I wouldn't get a smaller unit if you want to Crossfire later. If the Crossfire was intended to be now, you should get an HD 5970 instead. It's a little more expensive, but at stock speeds it's already 2 HD 5850s. However, the GPUs themselves are actually 5870s, so it can be overclocked to vastly outperform 5850s.

2. I don't think it's as big of an issue as everyone seems to think. If you get a bad board, RMA it. If you don't, then it's all good.

3. Ditch the Caviar Black and pick up a Samsung Spinpoint F3 (500 GB or 1 TB). They'll be faster and cheaper/GB.

You can save a few bucks with a cheaper optical drive. Newegg's cheapest is $25 shipped.

4. That RAM is fine.

I'm not sure what specs you're looking at. The 750HX has four 8-pin PCI-E connectors. There's no need for the silly adapters with that PSU. In fact, you could save some money and go with this PSU if you wanted.
