So I built my dream system Intel 6850, nvidia 8800 gt, 2G Ram, gigabye quad 6 mobo and all was well. Right out of the box I got 3D mark scores of above 14,000 and ran Crysis at very high settings no problem. 6 weeks later I am lucky to score above 5000 on 3Dmark and I don't know why. I have updated drivers, tried increasing GPU clock with gigabyte utility and used ntune. Still no dice. I am a novice when it comes to performance enhancemanet and overclocking so any help would be appreciated. Thanks.
