Which vid card were you running? Few hundred ppd sounds like some ain’t right. I installed a EVGA GT9400 on my kids’ computer and can expect 800ppd from it. I rally like this card since it can run on pretty low wattage (300-350).....C
I have an ASUS EAH4350 Silent video card that I was hoping to use. I took it out of the machine and was Folding on the ATI Radeon HD3200 on the motherboard until I gave up on GPU Folding.
The ASUS is ATI based, but apparently not 100% compatible with the built-in video.
The system is running pretty warm right now, another reason I am using the motherboard video (but I don’t actually know how either video affects the heat situation). The fan keeps the temperature around 50°C, but if gets a bit noisy for my taste sometimes.
