I have a 7600GT (256MB) - no complaints at all. Its about as good as you'll ever get in terms of price vs power.
No idea what my mobo is (I've had beer and can't be bothered to go and look) but I'm running Vista with 1.5GB RAM and an 80GB hard drive, 7 case fans, plus a CDRW and DVD-RW off a 400W PSU. No problems.
