E6600 OC to 3,1 Ghz
But I think that G260 is too weak for the future ... playing at 1920x1200... or?
While it's your choice and decision to buy what you want, let me tell you this: You buy today's video card to play today's video games. You should not buy into the scheme of "future-proofing", since by the time the future comes, there will be video cards that surpasses the 4870X2 for $200. If you feel that the 4870X2 is worthy, by all means, get it. Playing at a res of 1920x1200 is no easy feat, but that depends on the game.
