the GTX 780 will feel and run like a nice upgrade over SLI 580's..
Would have to go gtx 770 SLI 4gb cards for a worthy upgrade
sorry friend but in this case you do not know what your speaking of...

If you really want to push the resolution boundaries you should be looking at 3GB 780's or 7970's and if you are looking at 770's then the 2GB versions should be plenty, at least in my opinion....
and in more detail I'm not sure SLI 770's will take full advantage of 4GB either, that's still up for debate and benches to prove.
think about this, the GTX 680 can't use 4GB of VRAM either so besides faster clocks
why do you think the 770 can..?
