I just started folding and I'd like to help out by leaving my system folding 24/7, but I'm just worried if it would kill my system running it 100% stress 24/7. I've heard many stories on folding killing GPUs, I don't want that to happen to any of my components.
F@H sees a 4870X2 as two separate GPU's but does not take advantage of cards that are crossfired or SLI'd, these must be disabled. There is no way to disable the internal crossfire link in a X2 card under Vista atm, supposedly it's possible under XP.
If you are running XP you have to disable the internal crossfire and run two different Folding clients like you would for a multi-GPU set-up.
If you want more PPD bump up the Shaders only, the core and mem have little effect and can be underclocked...
