if i were you i wouldn't waste my money on a ti500.....they're still very expensive, i believe 250-280, and g4 4400's outperform them a great deal and are about the same price....OR you can do what i did, which was buy a ti200 for 120-150 and overclock that sucker to ti500 speeds. i have mine currently at 260/550. stock ti500 speed is 240/500.
