Update (yes I'm still here lol):
Beta WUs (Windows only currently) are now out!

Can't seem to get any on my 4850 right now.. hopefully they'll get that up and running ASAP.
Very true. Chaotic stated a drastic drop, which led me to believe more than could be caused by switching projects, but you could be right. I would suggest going through this order until the problem is fixed:
1. Check Free-DC machine stats to figure out which computer is causing the drop.
2...
Just consider the fact that we, a team with 65 users returning work daily (according to Free-DC), are competing with Canada, a team with 240 users returning work daily. That is impressive. Excellent job TPU!
I considered turning a Cyrix MII (P.Pro/P.II competitor) into a cruncher once, just for kicks, but that thing was too slow to even run Linux. It was quite the relic, though - had a Cyrix CPU, a Quantum hard drive, and an integrated ATI Rage GPU....
The opposite will likely be true. AMD cards, by raw compute power, are way more powerful than comparatively priced nVidia ones, usually by about a factor of two. (For example, the HD 6990 has roughly 5 TFLOPs versus the GTX 590's 2.5) Folding@home, which was initially designed for CUDA (nVidia)...
Really? Where did you hear that? I did some quick Google-fu and came up with nothing...
And anyway, BOINC tasks for both GPUs and CPUs are double or triple-checked, with multiple computers performing the same tasks. I doubt BOINC would use GPUs if they didn't produce valid data.
A core with hyperthreading vs. a core without is about a 30% performance increase. Not huge, but significant. I agree with Hammer, though, your combo is worth a 2600k, hold out.
True indeed. There are differences, though. First, BOINC assigns credit roughly based on how much data you crunched, while F@H does not necessarily. GPUs are far more efficient in FLOPS/watt than CPUs, so BOINC crunching with GPUs is more efficient in work/watt and credit/watt, while F@H...
