I just cancelled the FE, I'm going to stick with the Inno3D. I actually prefer the looks of it and the card is so well ventilated/more surface area, that I can't see the FE being better. I've already got lucky with getting a card with no coil whine so don't want to risk that
I'm currently running 2750/5725 (which is +1000 on the memory) at 925mV. So slightly higher than the 865 I had it before, but although I didn't notice any micro stuttering or weird behavior at that low voltage, I didn't want to risk running it if the card was indeed trying to regulate it
