For the most part I am only going to be playing WoW on this rig, but I'm not sure if I should go for a XFX Double D Radeon HD 6870, or a Nvidia Geforce GTX 480. I benchmarked them and the GTX 480 seemed to come out on top on most of them. But I don't know like if it'll fit in the case, or if it's actually worse in actual use. So yeah anyand all help is appreciated.
So what's your budget? Also, are you open to overclocking? I'm assuming you are. Anyway, here's what I would change:
Case: Corsair 400R... better case for the same money
PSU: 750W is WAY too much. I'm sure you could stay with a 550W and be fine. Try a PC Power and Cooling 750W Silver rated, though... if you want to stay at 750W
HDD: Is it 7200rpm?
RAM: Make sure it's CAS 9 and 1.5v
Mobo: I'd switch to a Z68 Extreme3
CPU cooler: Hyper 212 Evo
GPU: I'd recommend a 6870 or a GTX 560 Ti... I'd seriously recommend getting an MSI Twin Frozr II OC version of the 6870, actually.
I'd say the budget is about $1300 and that includes, mouse, OS, and monitor. So really more like $1050 for the actual hardware. The HDD is 7200rpm. I'm not super open to OCing, althought I suppose I could have my cousin help me do it.
$60 more and you can play any game out there on high/max with a 7850. But if you're not going to play any game out there, there's no point in wasting money. Most people will overbuy on their builds because they buy unnecessarily expensive components and end up taking the price away from either their PSU or food (equally important from a computer building perspective ).
Why do you think that? Most things that are compatible with Windows Vista are compatible with Win7. A review said it installed fine on Win7 64 bit... look at the "most helpful" reviews. It's the second one down.
