for the antec and the thermaltake, the 2nd 12v connection is solely for the CPU, so the vid card should not matter.

for the corsair, the 2nd 12v cpu connection plugs into a gpu 12v location, it would depend more on the quantity of gpu's vs. the power of 1 gpu for this PSU

I guess what I am getting at is the other 12v cpu connector critical for overclocks in the 4.5GHz range?

I be speaking of the P55 mb specifically atm...
