I have an i7920@4ghz which runs anywhere from 20% to 60% usage. My 4890 typically always ran at 99% usage. I figured it's because that thing is a damn dinosaur so it's to be expected. Well I just installed my 265, latest drivers and I'm still getting 99% usage. My in-game graphical settings are the same and I'm getting about the same frame rates I was getting before on my 4890. What gives? I assumed I'd be getting almost a 100% performance increase. Is 3dMark 11 a good program to run to test the performance of my card to make sure it's working properly? Thanks.
