Guys, just a quick Q: I found a stripped 8800 GTS 640 (G80) in the trash

Did a ghetto haxxx0r mod involving an Intel boxed cooler and what can I say - it works

Anyway, I haven't been folding in a while due to my main cards being ATIs. But I noticed there's a GPU V3 client by now - installed, but the card didn't want to crunch.
Installed the old GPU V2 and it works.. does GPU V3 in general not work on older cards?
