Fastest GPU ?

[ToastedChip]

Just built a new haswell 4770K system ready for BF4. Been waiting to see what the new AMD cards will do but now everything seems abit confusing.

So.. My question is. Out of the following cards, which is the fastest?

7970 x2 crossfire
GTX Titan
7990
R290X

Im currently running 1080p but will get 1440p when the prices come down. Im sliding towards the 7990 because from what i can see at that price its the fastest option.

Yeh thats what im seeing with all the research ive done, giving me a headache. Wish AMD would just say how much the 290X is going to be :|

Another question. The 7990 is a dual card, does it use the full 6 GB of ram or only 3?

I wont be bothering with eyefinity, i do run 3 monitors but for gaming i use one, old skool lol. So Gibbo. Any offers if i order a 7990? like 10% off code Bought a lot from ocUK over the years.
