Best GPU Upgrade

[MatthewC1991]

Currently have 2gb 670s SLI

I only use one monitor at 1080p

what should i get too upgrade?

im sure il get about 350 if i sell both cards so looking at 780 ti or 290x

If 780ti which model should i get?

doesnt get amazing FPS on Ultra that i really want

would i see difference with a 780ti or would it be minimal?
