My PC is currently armed with:
i5-4670K @ 4.4Ghz
Gigabyte Windforce GTX 770 OC
Asus Maximus IV Hero
Corsair Vengeance Pro Black 8GB (2x4)
Corsair CX 600W
So my question is, is it worth to upgrade to the GTX 780 or just SLI 2 770's? I am looking for the best performance ONLY.
If you suggest SLI, what power supply should I get? Thanks in advance. Edit: Thanks for all the answers, I guess I'll get another GTX 770 and better PSU.
