Okay this may be old news for some, but I'll tell it anyway. I decided to chuck in another 8800GTS 512MB in my comp and I was pleasantly surprised that it actually beat a 9800GX2 which my mate has. Checked my score on 3D Mark Vantage, and it just about took the lead. If you have one of these cards and are thinking of getting another, it is well worth the investment
