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.

This Core 2 Duo thing is just two of the same old Pentium 4 thing, a marketing stunt, to get people buying Intel instead of AMD. But we all know AMD offers better performance and lower prices.
