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.

In my opinion, you should just look for an AMD product, they're fairly reliable, and they're a lot more inexpensive than Intel.
