So my setup right now is 3 monitors, main is a 24" and two 19", i only use the 19's for 2D stuff: IM, system info, extra browser, ect, no games or video watching.
I have two GTX 470 in SLI and only the 24" connected to it.
I have a old gtx8800 running PhysX and the two 19". My problem is the 8800 just runs too hot and uses too much power for what it does, it idles arround 60-70c
What is a good cheap card that I can set for dedicated PhysX and connect two monitors that will run cool in 2D mode
The 8800GTX is most likely running 3D type clockspeeds and thus heat output because you have it running two screens, this is an ongoing issue and seems to affect a lot of cards but I couldn't say if it affects all cards as I don't run multiple monitors.
