I am no professional in this area, although I have read about a similar subject to this. Running GTX 780's in 2-way sli, should be ran with atleast a 850 watt psu, and an FX-6300 is probably going to bottleneck the GPU's. I don't know what CPU you'd rather get, but you should definitely look into getting a better CPU. My guess is somewhere around an FX-8350.

Disclaimer: I am no professional as previously stated, this is all based on what I have read from other professionals, I am just forwarding tips and knowledge.

You have an FX 6300 CPU driving twin SLI GTX 780 cards? That's your problem right there. You have a killer GPU setup and a very sub par CPU at the center of it. While you'll need to upgrade your PSU to something 850 watts or higher, your CPU is probably a more pressing issue.

An upgrade to an FX 8320/8350 will do you a lot of good. As will a better PSU. Between an FX 8 core, and SLI 780's your system will be drawing a huge amount of power.

I mistook you for the OP. Why are you posting questions on someone else's thread anyway? Make your own thread asking your question.
