Two weeks ago I scored a 2533 in 3D Mark 05. Two weeks ago. I upgraded my ram from 512 to 1024. Joy. Been two weeks since then. I installed everything into a new case, added a new 7.1 supported sound card and upgraded to a 500 watt power supply from a 300 watt generic power supply. Something I thought would be good. I scored a 1565. How is it that there is a 968, almost 1000 point difference in my scores? Defragmenting doesn't help, ran Adaware, Spybot and Spysweeper. Nothing is running in the background. What the heck is the problem?
