Have I downgraded instead of upgraded
My old card bought a few years ago was a Gigabyte ATI Radeon HD 4850 512MB.
I just bought and installed a ASUS EAH6670 HD 2GB. Updated the driver using AMD driver utility. Tweak the card to game mode using ASUS GPU tweak.
Before I removed the old card I ran 3DMark06 and got a 3Dmark score of 10053. Ran it again with the new card and only got 8136.
Can anyone give me some idea what might be wrong? Surely the new card is a better spec and memory and should give a higher score.
