Which stepping is the i7 920? The D0 overclocks much better than the C0 stepping.
But if they're the same price (including the price of the motherboard) I'd say go for the i7 920, mine still plays all modern games without any problems. Or if you can find an i5 2500K or 3570K for around the same price then go for those because the 920 is already 2 generations old and a bit of a power hog.
and a core i3 beat a 4 core unlocked amdIntel processors are really hard to beat. I read an article where a 4 core Intel beat a 6 core AMD. For gaming I think the Intel processors are better.

well that would depend on the game, most games are still unfortunately dual core optimized, but I can say after gaming on my friends i3 2100 and then going back to my phenom II x4 that I can beat him in games were quad cores are truly utilized, both of the cpus can take games to well beyond 60 FPS making the choice less about performance and more about cost.
