So, what's a good gaming rig these days?

He's also willing to sell me a 560gtx for about $100.

Too high. I picked up a pair of 570's for a little under $180.- last month. A 560 should be around $60. Ti version maybe $10.- more. Only a 570 or above is going to give you a big improvement over your current 460.

@Kalmah you gotta be having some problem not cpu-related; i'm playing Borderlands 2 on high settings @ 1920x1080 and it's smooth as silk. E6600@2.4Ghz.
