Do what i did sell on the 3930k, Mobo and Ram I got £600 for it with the water blocks Greg
Update to X99 and get a titanX then you should be close to a 2nd card.
Do it greg, 2 titan x's on an x99 (what I'll be doing) will be awesome.
I did game at 4K and that was real lush, so I won't discard that option either and with that comes less work on the CPU, so less potential bottleneck. There is so many variables and I just don't know what to do. I also know that DX12 will make our current older gen CPUs feel like a 2 gen upgrade, so that is in the back of my head as well.
I am leaning towards 2 TXs and sitting with what I have for now. I can't afford to get 2 and X99 in one hit, so I will see how the TXs get on.
