there are 2 Issues atm. 1 about the micron memory, which you can fix with a bios update (as far as i know)..and this one, of course it does affect all cards. It doesnt have to affect all users. It depends what type of games you play, if you overclock, benchmark etc. I guess it may only become a problem with high power draw.
However, i think the RMA-sendback-rate will be outstanding high with this FTW series. Its not the gpu-temp that kills cards over time, but the temperature of the pcb and the soldering, the very high temp-differences put a lot of stress on the vram and the solderings all around the gpu-socket. But with EVGA at least you should not get a problem when you have to return it.
