Core duo

So i'm building a second pc just for games, and i've heard a lot of good things about Intel's core duo line for this, anyone have any experience with this?  The prices aren't bad either, between tigerdirect and newegg there's always one on sale.  If you have any other recommendations (besides no vista, obviously) for a gaming pc, please throw that in too.  Mind you, i'm on a budget, maybe around 1300 dollars max.

E6400 will do you fine (Core 2 Duo) though an E6600 is the real sweet spot. 2Gb RAM. Big arse SATA drive (raid is for posers if it's a game machine). Minimum 7600GS vid card. Dedicated sound (5.1 is still fine and cheap as poo). 500w PSU.
