Im doing a new x79 chipset build and Im on the fence between 2 MSI Gtx560 ti Hawks in sli vs 1 MSI Gtx 580 lightning. the sli outperforms the single 580 lightning but,not as future proof as the possibility of another 580 added later as you cannot triple sli 560ti's . price difference is $8 more for the 1 580 vs 2 560ti's...thoughts?
In addition, would a corsair Hx 1050 PSU future proof this setup for a dual 580 lightning sli down the road. thank you all in advance.
You can probably sli dual GTX 580s on a 850W PSU, but 1000 W will be a more comfortable rig (PSUs like to run 50-80% of capacity). I have the PCP&C 950 W running dual GTX 470s, Their requirement is for 225 W apiece. With my other components I draw about 600-700 W and the PSU is not straining. I would feel comforatble with a quality 850 W PSU.
