Next Upgrade?

[Camaro]

Hi all, my specs are listed below. I just upgraded to a 4GB EVGA GTX680 and found about a 20% improvement over my HD6870CF setup. My 3dDMARK11 score was 9053 which seems a bit low compared to others I've seen.

-My question is, is it worthwhile to upgrade my board and processor? I might be able to squeeze out 4GH from my i7 920 but I would like to get a board that has the latest USB 3.0 and SATA 3.

-Do I make a move or is it better to wait? Thoughts on what a significant upgrade would be?
-Lastly, if I go with a more powerful CPU or add a second GTX680, will a 700W power supply get it done
Thanks so much,
Mark

Let the system run for 1 year, than upgrade to it just after crysis 3 arrive. Crysis 3 will require a lot more cpu i think.

So no point in upgrading the board them I guess. What about the power supply? If I add another GTX 680, will 700W get it done?
Thanks for the help!

A quality 750W PSU like a Corsair AX750 will do just fine for 2x gtx 680. But i think you should buy more than 750w, like 850w for future system upgrade.
