2 X GTX 760 SLI vs Radeon HD 7970 vs GTX 770

[cerefo]

Title says all. I am going to use a 40 inch HDTV and will be playing hardcore game in ultra settings on 1080p, I'll also be doing hardcore Multi-Tasking. I just want to know that which is the best among 2 X GTX 760 SLI vs Radeon HD 7970 vs GTX 770
If you have any other choices then tell it also, but make sure you tell me the pros and cons among the 3 above mentioned
Please suggest me which one is best as per my specification.

Its better to wait for the AMD new generation of cards. And some say it will be better than the titan and a bit lower price than the 780

I'll surely wait, but for now, can you suggest me the best option?

Why does your poll choice not reflect the question you asked?

that's because the poll can't be edited! and thus I can't update it to new GPUs that I am now thinking of and that is the thread title (which has also been changed)
