I figured I'd make a post about this since I'm out of ideas. First my specs:
q6600 oc'd to 3.5ghz
corsair hx 750 power supply
8ghz of ddr2 gskill @800mhz
asus p5e x38 mobo
two HDD both western digital 7200 rpm
XFX 6870 crossfire
When they first came out I had an older card. So I picked 1 6870 up and it worked great I was impressed with how well it ran. When I heard about how well it was supposed to run with crossfire I picked up another since my mobo is able to use crossfire and both of my pci-e slots run at x16 so I thought it would be worth it. In benchmarks I've done such as heaven or AVP the framerate is pretty much double and everything is very smooth a definte improvement but when I test them out on bfbc2 which is what I have been playing a lot of lately it seems like 1 card actually ran it better.
Now I understand that with crossfire setups you are supposed to get microstutter? I'm not really sure exactly what it means as this gets thrown around a lot but I was under the impression that it was a noticeable stutter in between frames that made everything look really choppy. I don't have anything like that.
What originally occurred that I noticed was when I would run bfbc2 the frames would be double and the gameplay would be somewhat smooth except when I turn ingame it would be like I was turning with a constant rate of about 25-30 fps not a super big problem but it definitely affects game play. Now it seems like when I run it that with 1 card I'm getting higher frames and when I put AA and AF on 8X through CCC and texture filtering on high quality, the single card runs smoother and gives me better frames. I've heard people say this is a negative point of two gpus over one but it seems to vary as well.
The things I've done to try to isolate the problem was I tried each card solo in both of my pci-e for days and they both ran great not a problem although I noticed a slight hint of one running a little smoother ingame than the other, other than that was fine.
I've tried pretty much every driver under the sun. Currently just stuck with 10.12 but I went back to 10.11 and the bit of slow response time I was getting when I would turn ingame almost 100% went away. It worked out great and I was planning on just leaving those drivers but about every 10minutes the computer freezes. So I went back to 10.12 with the lower performance. I don't know if it could be the drivers. Or if maybe my q6600 has something to do with it? Is running crossfire going to put a heavier strain on your cpu? I know that bfbc2 is very cpu intensive game and maybe me running two gpus strains it to the point where it puts it over the edge and maybe its only making 20% use of the 2nd card or having to slow down altogether. Just speculation I really have no idea at this point. Figured I'd ask more enlightened individuals XD
Anyways I think that's enough wall of text. I appreciate any help or even just info anyone could throw my way. Thanks again.

O you think they will make DDR2 boards for the new bulldozer's and sandy bridge?
