I just picked up a 4870x2 to replace my GTX280 (maybe) and I tried out Morrowind heavily modded of course and my framerates are terrible. I'm talking possibly less than half the fps of what I was seeing with my GTX280. Is that normal? I ran GPU Tool for a while with no problems so the card seems fine. One other question. Should I reinstall my OS? Ive heard of too many problems when going from Nvidia to ATI hardware.
