So I originally had a EVGA GTX 560 but now I have a HIS Radeon 6990. I was currently using the EVGA precision software,
that detects GPU temp, usage, fanspeed, and fps. Is there a similar program for Radeon cards?
Yeah, MSI Afterburner is probably the best. It gives you manual fanspeed curves, overclocking, and just plain monitoring. It was made by the same guy as Precision apparently, it's free, and has many more features.
