Higher the OC, lower the score?
Ok so I'm trying to OC my 6600GT PCIE card to get the most out of it before it gets totally obsolete. On stock cooling I've had it OC'd to 570/1100 and I score a respectable 3890 on 3DMark05, which is the highest I could go. But my temps were about 55* @ idle and 70-75* @ load, so I wanted to cool a bit more. I purchased a Zalman VF700-CU, installed it, and temps are down to 45* @ idle and 55* under load. So I OC'd it to 580/1200, still reaches the same temp, and seems stable while playing games. Yet, when I benchmark it with 3DMark05, I now get a consistent score of around 2500? Any idea why performance has gone down? Latest driver is installed.
