We ran 3DMark 11, and my system came out miles ahead. None of our components are overclocked - all standard, and the benchmark was using the same settings. My overall score was P7526, whereas she got P3793. The only score that her system beat mine on was Physics (she has PhysX, of course, being an Nvidia card), but even there she only just beat me (6330 vs 6274). We ran another benchmark - MSI Kombustor - and at 1680 x 1050 she only got 22FPS, which seemed very low for a current model card.
I ran the OCCT GPU:3D test, and at 1680 x 1050 fullscreen, with shader detail set to 7, her system reached about 138FPS.
I installed FRAPS and played Assassins Creed III at maximum settings, at 1680 x 1050, and she peaked at about 59FPS.
This seems a bit weird to me. It seems like 3DMark 11 and Kombustor are not working properly. The card itself seems fine, and while we haven't tried Crysis or something similar on it, it seems to be handling things alright. Should we expect more from the card, or is it just a software glitch in these benchmarks?
