Best Graphics Upgrade Option For Me?

[STYLZ]

I just bought a GH4 and want to get better performance/rendering for my 4K files in PP CS6/Resolve. I currently have a GTX 660 Ti GPU. Question is, would it be better to get the same card and use SLI or would I get better performance if I just upgrade to a EVGA GeForce GTX 960 SuperSC?

Side note.
I have
16GB RAM DDR3 1600
I7-3770 3.4Ghz processor

CS6 has no SLI functionality, so you're definitely better off with the newer card.

Just remember that not everything is accelerated. Whether or not you see any improvement will depend highly on the things you do.

Roger that. Thanks.

Maybe another 16 gb ram while you're at it? AE and Speedgrade can use a lot of RAM...like up to 25-30GB...especially AE. Premiere, not so much.
