Hey guys,
I need some advice. I could get 2 gtx 580 OC 1.5gb for around $450

. Would this still be a good investment? or just get either a single 670 or 660Ti? or even a 680? it's very tempting because it's like half of what it used to cost (per card) but I understand that they've already discontinued this model.
Also, how much of a power beast are these cards? i understand under load they are around 500 - 600 Watts but translated to elect bill terms; would the increased power consumption cost be very considerable?
Thanks!
