Well, the HD 4870 X2 has an issue since with the newer drivers you can't disable Crossfire on the card.

My mistake, should have realized you would be running them at stock for testing. For comparison, my fact. OC'd 9800 GTX+ will do ~6150 ppd with the shaders at 1978 MHz running that WU...
As far as I know they haven't found a way to utilize both GPU's on a 4870X2 running Vista 64bit yet, I'm not even sure about 32bit, you would have test it using XP...

With one of the beta drivers reviewers were given, we were able to disable Crossfire and have the card recognized as two separate GPUs. Unfortunately, this isn't an option anymore.

That is unfortunate, did a quick check on the forums and didn't see any way to get Vista to disable the internal crossfire. There are a lot of Folders that would like to get their hands on that beta driver if it would work for F@H, otherwise its XP only for an X2 Folding both cores...
