Folks, I flashed my PNY 6600GT(Nvidia), to unlock a temperature monitor on the card. Also, flashed it with a "modded" bios. Turned out great. FR's much higher, stable, no problems after several hours of playing.
It was something that I was wanting to do for a long time, but was a little wary. If anyone is interested, let me know, I'll give info and what's needed to properly do the trick.
Note: ATI's can also be flashed.
