So I bought a new graphics card in may, specifically this one:http://www.newegg.com/Product/Product.aspx?Item=N82E16814150590, and it runs the majority of games on high. However today I was running some stress tests and it showed my score on FurMark as only 2200, and when i looked at some other 7950's they were around 3.2k score. When look at the the graphics card in gpu shark it says I have two performace states, one at 300 mhz and the other at 900 mhz. But then it says that I am currently running at 500 mhz whether i'm doing a stress test or not or even playing it game it doesnt change. I have not overclocked the card at all or changed the setting and I am currently running the most recent drivers. What do I have to do to make the card run at 900mhz?
