Hello I'm almost done building my computer but the problem is I'm stuck between these 2 options. The crossfire 6970 which I will get with i5 2500k or the gtx 580 with the i7 2600k. I just want to say which is the better buy. I know the two processors are almost the same for gaming but i want one that is more future proof, but will the 2600k just become obsolete in the future at the same time as the 2500k. Should I just get a new processor then? But on the other hand if i get a gtx 580 (used by the way), then I can just switch out the graphics card and save the money for future use. But the performance increase is really good for the 6970 crossfire. The crossfire 6970 is $619. 98 with rebate while the gtx 580 1.5gb is $410 (3gb is $495, should i get that instead if I'm getting gtx 580).
Two 900 Mhz 560 Ti's toast them both for lot less money.

since your talking about going crossfire with 6970 it is good, 580 is good specially the 3gb one for more future proof, if you plan on getting a new monitor too and you can add one for SLI which can give you a good gaming experience or other stuff you want to do with it. specially if you don't plan on overclocking any
