Yeah, but two 560's amount to the price of one 580 whilst I'd be paying more than $1000 for two 580's :/
I could always get one 580 first, then just get another 580 down the road and sli it.
That PSU seems like a great deal to me. 850W and gold certified. 850w is overkill, but if I'm powering two firmi's that might not be the case. My case is riced up blue anyway, so it'd be nice to have a blue light emitting from the bottom as well
Thing is two, I can also go 3 monitors with sli. Although the quality won't be as great as eyefinity.. The option is always there.
