What kind of improvement?

What kind of improvement can I expect from a AMD triple core @ 2.1ghz to quad? And how much fps gain in games? please recommend quad cores and what the difference would be! Also I need a new mobo, what should I get and will it add improvements to gaming? like increase in FPS? How will it do with crysis warhead?

in a year or more a bit of difference but as of today not very much.

Anyway 3 cores just sounds wrong :D

you'd only see a difference in programs that use multiple cores. for most gaming and everything else, no difference.
