That clarifies things, thank you.
On a related note (I posted this in the Batman thread as well), I'm not too thrilled with overall gaming performance. I've had a hard time determining if I'm not getting the performance I expected out of a Crossfire setup because games/drivers aren't optimized for it or because my AMD Quadcore CPU is being a bottleneck (as opposed to, say, a system with the intel i7 2600k CPU).
I'm considering selling my two 6950s, buying a GTX 580, and going with an Intel setup.
I'd bet its the CrossFire setup. AMD isn't updating the Crossfire Application Profiles (CAP) fast enough and unlike nVidia, you can't make your own. Even then, the performance gain isn't nearly as much as with nVidia. HardOCP has been running image quality and performance comparisons between nVidia and AMD lately, their Skyrim
one is pretty telling. Here is their Batman: Arkham City one as well.
I just switched from a 5770 to a GTX 560Ti 448 Cores (a 570 Basically) and am really pleased with the difference. nVidia just has better products for games, AMD has better products for photo editing and multi-display setups.
I doubt the processor is really making much of a difference, most (if not all) games are significantly more limited by the GPU than the CPU. Replacing the 6950 with a 580 (or 590) will get you a bigger difference than changing from AMD to Intel.
