I will say this, Nvidia dictate partners what they can and cannot do, AMD don't.
EVGA are good in terms of service and quality, those things can be matched, and sometimes are.
EVGA could be much more than they are, if it were not for Nvidia telling them to limit volts and overclockability. In that respect they are just like every other Nvidia GPU.
No choice at all.
Asus on the AMD side have a 7970 with 1.4v out of the box, more VRM's than you can count and a cooler the size of a brick. it sets them apart from all the others, it gives you choice, some will only overvolts to 1.25v, others like my Powercolor will do 1.27v, my Gigabyte does 1.3v, the high end Asus does 1.4v
The potential for a VRM city 1.4 volt GPU is huge.
Meanwhile Nvidia are forcing everyone to remove the more fancy overclocking stuff and conform to a standard.
EVGA are not allowed to have an edge, thanks to Nvidia. it completely takes the sheen off EVGA.
I think EVGA would like to compete in the AMD space, but are locked to Nvidia only, for whatever reason.
