Man I don't understand what's your problem? RT is a free software. You like it, you use it as it is. Are you a power user? If yes that fancy EVGA voltage tuner already exist in RivaTuner so no complains. If no wait for OMG FTW XXX EVGA Voltage Tuner. Simple as that.
And indeed you should show at least a little respect for Unwinder's work because he give you a very powerful tool for free.
Sorry for my offtopic but I though that here on XS I don't see that guru3D "Unwinder is jerk/rude/whatever" attitude. Obviously I'm wrong.
