You could probably pull it off for under $1000
Well, I'm not computing using my GPU, I'm using all my CPU. I set up an SMP client (with the help of FreakingHell) and am using all 8 cores of my i7 920.
Maybe you should think about using that GPU of yours.FreakingHell helped me out as well getting the VM working.
Just got that spare GTX260 folding but now I need to get my 4850 back up and running...

Do I need another folding program to set it up for my GPU? If there is one, can you direct me to it? And if there is one, can I run it at the same time as my CPU? I only have 1 4870 right now (1 of my 2 died) but I'll be getting a 5870 soon.
This sounds like a giant botnet, no thanks.

I am running windows 7. I just downloaded the first file at the top of the high performance downloads page (the "Windows: V6 GPU2 (ATI 2xxx, 3xxx, 4xxx; nVidia) clients" one), and ran the setup. Now I am running the VMWare and the GPU Client at the same time. I didn't set the GPU to a higher priority, I set the CPU usage of the GPU client to 0% (As to not hinder the progress of my SMP client). Is there a better way to do it than that?Yes you need another client. Yes you can run it at the same time as your CPU(but make sure the GPU client is set to a higher priority than the CPU client).
Are you running XP or Vista?
