For those wondering, and to bump this completely awesome thread, you can get the GPU client here and it's rumored to be up to like 70x or more faster.
Going to run both the SMP CPU and the GPU overnight for a few nights and see how much I can produce.
I encourage everyone to do so. Reason being is that on my 9800 GTX+ I didn't even notice a performance hit, and I'm sure those with epic GPU systems will not notice, even more.
Plus, you can feel good knowing that you contributed to a completely awesome cause and all you did was run a program while you watched explicit videos or played cool games.
