First Build Advice

[Sanderz]

I was going to go through jack's list and link to newegg, but some of the parts really depend on what you choose for cpu/mobo/gpu. I'd probably pick these three for your budget:

CPU: http://www.newegg.com/Product/Product.a ... 6819115072
MOBO: http://www.newegg.com/Product/Product.a ... 6813131729
GPU: http://www.newegg.com/Product/Product.a ... 6814161372

As for the power supply, I agree with Jack on the ranges. You could probably go a little lower (500-550W) with an AMD card simply because it draws less power than a fermi at load. I'd still go with a 750-800 for possible expansion. Higher wattages will have more rails for things such as hard disk drives and dvd drives. As for brands, I usually go with Antec. Corsair is fine too. Another thing to look at is if you want modular cables. It'll cut down on clutter which will keep your case cooler, but they usually cost 30-50 more than regular PSUs.

Edit: actually the GPU will probably put you over budget since those three are around 650. RAM will be 50-75, a 1TB WD caviar black will be 130, and a PSU will be around 100. If you go down to a 6870, that would be 80-90 dollars cheaper.
