Ah okay that sounds logical
Last time i got a bit over my head
The set up i have now is
ASUS Rampage III Extreme, Socket-1366
Intel Core? i7 Quad Processor i7-950
I found myself doing the same thing this time around. I bought the X79 and a 3930K (going from the X58 and an i7-960). I didn't see a whole lot of improvement with gaming. It's a solid platform more so for many purposes outside of gaming, but many of the features you pay for are not necessary for a gaming system. Since I find myself gaming on this machine more than anything, my next CPU/mobo combo won't be marked as "enthusiast" like the X79 platform but rather a mainstream like ivy bridge or Haswell. I'm really not incredibly impressed with Sandy Bridge-E from a gaming standpoint.
Moving to the Haswell architecture and an i7- 4770 wouldn't be a bad idea because of the inherent speed improvements over the older architecture, but you'll get the best bang for your buck by simply adding a GPU to your current setup.
As a matter of fact, if you're having no issues with your current CPU and motherboard, you might just pick up the additional 670 first, run SLI on your current motherboard and hold off on the architecture upgrade until Intel really comes out with something that's a real jump in improvement over your current architecture. You will see a big improvement in your visuals and capabilities with two 670s on your current board.
Just another option for you to mull over.
