I have the GTX 460 and recently got the i5-760. This thing flies at 3.91ghz and 880/3800 for the video card.
Even at 1280x1024 the HD 5770 can't do anti-aliasing beyond 2x so it's garbage.
Get a i5-2500K; I had a gift card and didn't have much of a choice.
I bought the i5 just before the 2nd generation came out.
Would a GTX460 or HD6850 handle newest games and few years further smoothly?
