I'm running a Phenom II 965 and it kicks butt. The 470 is good, but runs warmer.
For the same price, I'd got with the 2500k and the 460. It'll keep you future proofed for a long time.
My PC:
Phenom II 965 black edition, 4 gig 1066 ram, 2 hard drives, dvd burner, 620 watt PSU, sound blaster x-Fi gamer, GTX460 superclock 768mb.
