The HD 4870 and GTX 260 are very close in performance. For example one wins in Crysis and the other in World in Conflict, but they change relative positions depedning on AA level and resolution too. Either will be enough for the next two years IMO unless you're playing on a 1920x1200 monitor and want lots of fps.
Crysis:
With AA on, the HD 4870 wins by 2 fps. With AA off it loses by 2 fps. That's a tie.
World in Conflict:.
The HD 4870 wins by 5 fps without AA and by 7 fps with AA. That's a win for ATI. Not big but it can be noticed. (38 fps vs 31 fps).
Devil May cry 4:
The HD 4870 wins by 7 without AA and by 5 with AA. This is actually a tie because the GTX 260 gets over 100 fps anyway and you won't notice a difference between 122fps and 129fps.
It depends on game, settings, resolution. If you play at 1680x1050 and enable all the eye candy, then the video card will get a chance to show what it can do and the CPU will matter less. Well, you were going to do that anyway, weren't you
Tell you what: buy the card, install it, download FRAPS, play one of the usual games for which you can find benchmarks easily (Crysis, CoD4, UT3, Oblivion, etc.) If your numbers and the numbers on the Web are very different then you have either a CPU bottleneck or a PCI-E 1 slot bottleneck. Maybe you won't have either. If it's bad, you can wait for a Nehalem MB+CPU or get something like GA-EP45-DS3L or Q6600 or both.
