So, for anybody that was following my previous thread, it turns out one of my cards was DOA, and only running at 2x bus, preventing the cards from going into CF. So, the card has since been exchanged for an Asus 5850. The setup is in CF just fine, but I now have a new problem. I seem to be getting low Heaven benchmark scores compared to others with similar setups. Here's the latest stats:

Heaven Benchmark v2.1

779
Min FPS:
11.0

ATI Radeon HD 5800 Series 8.762.0.0 CrossFireX 1024Mb

Additionally, logging in MSI afterburner shows that, while GPU1 usage maxes out during the benchmark, GPU2 is almost at idle the entire time. Now, I do get a performance increase in CF. Namely, I score around 400 with a single card. The scoring just seems low to me, as most are getting in the 1200-1300 range, and at a higher resolution than me. Any help is appreciated.

Have you updated or installed your CrossFire profiles?

Hmm, that's fine by me. I just haven't gotten around to it yet, and I bought it to OC it. I'll have to give it a try tonight.

OC'ing didn't do anything to improve the performance. I took the processor up to 4Ghz, and no change. Again, it seems like the second card isn't even doing any work. Going by what MSI afterburner is saying, GPU1 is showing a full load, while GPU2 is almost at idle (only a 15% bump in load here and there). The cards are in CF, and seem to be configured fine.

So, I figured it out...silly mistake. Catalyst A.I. was disabled, essentially shutting down the second card. Once I enabled it, things got a bit better. Here's the new numbers.

A little Better? From 30 to 58 FPS is almost double... But then again, this thread is way over my head. I just bought a single 5850 today. How do you like yours?

I love it, great performance for the price. And the "little better" comment was very tongue in cheek.

I have had my card for a few months now. I love it. Didn't have any major problems since having it and a huge improvement over my old NVIDIA 9800 GTX. When the 6000's series come out. Hopefully the price will drop so I can pick up another one for cross fire.
