Something is probably wrong with my graphics card

. I've posted in here before but my ASUS DirectCuII 580 does not show 100% usage in a lot of games. The only one it seems to do it in is Crysis 2. Last straw was GTA IV. People in the ice mod thread are getting better performance with similar or less hardware than me. Sethos has been helpful and ran the benchmark test in the game with similar settings and he was avg 58fps and that's with the ice mod. I downloaded 3DMark Basic 11 and read the tests (@ 720p) and it says :

I've went up and down with drivers, made sure the power was set to maximum, no overclocking etc . Am I gonna have to RMA my card?
:([/QUOTE]
if I run my GTX480 at stock clocks (4.8ghz 2600K) I get
3DMark ScoreP5750
Graphics Score5254
so your score seems pretty normal to me ... keep in mind that lots of people submitting scores are (heavily) overclocking, which shifts the expected/average score upwards
else run something like Unigine Heaven Benchmark (very gpu dependent, cpu hardly matters) and compare to someone who ran the exact same settings
for constant 99~100% GPU usage you'll always need to turn off V-Sync ofcourse
