GTX 760 good for Nextgen games?

[Warsna]

Hey I'm looking at upgrading my GPU on my PC so that it could run nextgen games. I currently have a GTX 550 ti. It can run most games well but the higher graphical intensive games it needs to be put on low settings in order to get good frames (40-60fps on Bf4 and AC4 Black Flag). Is it worth upgrading or should I wait a bit more. Thanks for any suggestions!

960GTX is coming out soon, i would wait for it. Should have 4GB and higher performance while still keeping 250$ price range.

Ok, I would also need to get a better PSU while getting that graphics card. Which one would you suggest?
