I just got Burnout Paradise and I started play single player. Instantly I noticed that my pc seems handicapped. With one card, I get 40-50 in closed areas, and 20's in areas where the city is open and you can see far away. With two cards, exact same performance.
My settings are the High settings, I've tried all the AA settings and they don't seem to impact the performance. SSAO is off.
I recently reformatted my harddrive because of really poor performance. I thought one of the problems might have been that I had installed a second 4850 which I got back from visiontek after I RMA'd one of mine that fried.
Here's the previous thread I wrote when I received the second card.
I don't really care about that issue anymore unless that could be an indication of that problem.
I decided to benchmark the cards to make sure crossfire was working. I didn't want to download all of the 3dmark06 so I dled FurMark.
Benchmarks:
FurMark v1.6.5
These definitely indicate that crossfire is working.
I also downloaded GPU-Z to display some statistics about the cards..
Here they are
When I installed CCC and the drivers, I just did it once, I didn't put in a card, install drivers, take out a card, put in another, install drivers again.
Hopefully I posted enough info that you guys can help me out, it will be much appreciated!

I bought two last summer. One of them fried and I just got it back. I noticed that the card I just got back idles at stock speeds (625/993) compared to the one that I haven't had an issue with which idles at (500/750). Can anyone explain to me why this is and what I can do to get the second card to idle at lower speeds?
