I threw up 2 939 combos on my FS thread but I'm doubtful anyone is going to be interested. Probably going to get raped over shipping charges anyway.
I assume I am...it's just running on an i3. When I get my Xeon DP setup (either Thursday or Sunday, most likely) then I'll move the HD7950 to it and put the GTX460 back in the i3. I figure that way I can run 10 WUs on the HD7950 at .7 CPU cores each and then have 1 WU running on the CPU (currently doing 8x.667 on the HD7930 and i7-860).

I'd be interested in the S939s if I didn't have such easy access to C2Ds---when I can get nearly a complete 2.4GHz C2D system for $20, it's hard to justify buying similar stuff.

Basically, you create a file called app_config.xml that tells BOINC that the HCC GPU app really only needs a fraction of a GPU to run on. For powerful cards, it boosts the output significantly. The ideal number of WUs/GPU is experimentally determined.
