If Maxwell has been delayed till 2015 I might buy a 780 Ti but I would prefer one with over 3gb. 6gb would be great. Also how does a single 780 Ti compare to 2 670's in SLI?
I'd say get two 6GB 780's over a single 780Ti. My 780 at 1254/7100 is about equal to a 780Ti reference and my 670SLI setup still has more grunt (they are at 1280/7308).
^^ definitely a good option. It will be interesting to see if/how Nvidia release the 6GB 780TI now that Titan Black is out there.
