GeForces are actually less compatible than Radeons according to Alias -- but my experiences with GeForces shows they're fairly easy.

Personally I'd softmod either a Radeon or a GeForce to a FireGL or a Quadro depending on what you got. Several cards are unmoddable though.

For certain GeForces: https://forum.simplymaya.com/showthre...threadid=17109

Again, you void your warrenty and there are some cards which won't work (including anything with 7800 printed on it)

And yes "Increase" is a typo, I meant to say "decrease your render times"
