Hoping someone can chime on a potential problem I may have with a Zotac GTX 580 Amp!. I recently purchased this card and did the Windows performance check to see how the new system compares to the older i7 system I had. Everything checks out except for the GTX 580 which rates at a 4.2 for 2D applications and 6.2 for 3D applications. This seems a bit low to me as my dual GTX 275 did better than this. Any insight would be appreciated. System specs: i7 3930K stock Asus X79 Sabertooth Kingston Ram 4x4 @ 2133 Seasonic 800W Zotac GTX 580 Amp! Stock.
