If you have been wondering how the two flagship GPUs fare in a battle royal of pure frame rate you can satisfy your curiousity at [H]ard|OCP.  They have tested both NVIDIA's TITAN and the finally released HD7990 in one of their latest reviews.  Both cards were force to push out pixels at 5760×1200 and for the most part tied, which makes sense as they both cost $1000.  The real winner was Crossfired HD 7970's which kept up with the big guns but cost $200 less to purcahse.

If that isn't extreme enough for you, they also overclocked the TITAN in a seperate review.

"We follow-up with a look at how the $999 GeForce GTX TITAN compares to the new $999 AMD Radeon HD 7990 video card. What makes this is unique is that the GeForce GTX TITAN is a single-GPU running three displays in NV Surround compared to the same priced dual-GPU CrossFire on a card Radeon HD 7990 in Eyefinity."
