Hello,
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 could try, if you can find them, GTX 470s or 480s instead of the GTX 560 ti's. You can run a triple GPU SLI with the 470/480s.

Putting a GTX 470 in sli (2 cards) scales up to about 185% - 195% over a single GTX 470. I believe that adding a third card will not produce much more than 20% over the dual rig.

A GTX 580 requires approximately 244 watts (see: http://www3.pny.com/support/media/Files%5Ce4d9a796-96c0...)

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.
