Additional Comments: This is my first build and have been looking at components for a couple months. The HD 6950 2gb is supposed to scale better than the gtx 560 in crossfire mode and can come close to the gtx 570 sli. Im hoping that this build can last a couple years before needing replacement parts, which is why i am getting two hd 6950's for crossfireX mode. Also, a i5 2500k OC'd to 4.5 ghz will be faster than a stock i7 2600 right? Lastly, the sapphire dirt 3 addition has a dual bios, so can i unlock the shaders and overclock to 6970 levels if i need a few extra fps? Any comments and suggestions would be greatly appreciated.
Looks boss. This'll definitely last you a while.
The 6970 unlock is worth trying.
I don't think you need three additional fans. One or two would be plenty.
Yes, an OCed 2500K is way faster than a stock 2600. It's roughly equivalent, in gaming, to even an OCed 2600K.
