Good afternoon,

I've read online that no matter how powerful your GPU may be, if your CPU is not up to par, it will bottleneck the system. I've been looking to buy another GTX 960 or even a whole new GPU all together such as a GTX 1060 but am wondering if the i5 would cause any sort of issue. If yes, then I would rather just get a new i7-4790K and hold off on another GPU. I'm looking for some opinions on whether another GPU or a new CPU would benefit my system more.

Another thing I am worried about if I do decide to do SLI, is whether or not the load on my CPU would increase that much more. Would I need to change the CPU cooler to an AIO cooler such as a Corsair H100i instead?

I guess a thing to note is that I am using this system to play games and just some light work on the side. The game i am playing right now is Black Desert Online. At max settings I am able to run the game at 40-60 FPS with dips into the 20s depending on what I am doing at that moment. I would like to be able to, at the very least, play at a stable 60 FPS but ideally, go above that.

Thank you. Cheers.
 
Solution
Personally, I would opt for a faster single card within your budget. SLI will indeed be up to 80% faster than a single card. But SLI (and CF) is never quite as smooth as a single card. Some games just don't scale well with dual cards. Some do and they perform amazing.
The GTX 1060 6GB is on a par with the GTX 980

That would be my choice.
