R9 290X beat GeForce GTX Titan at 1920x1080, 2560x1440, and 3840x2160. So what the heck happened at 7680x1440? Check it out:

Radeon R9 290X is getting beaten up by the workload with one card. With two installed, it spends most of the run just sitting at 727 MHz (72% of its rated clock rate). Now, again, I have to concede that achieving this performance level against $2000 worth of hardware from Nvidia is still phenomenal. But it's such a shame that AMD can't get more from this GPU. At any rate, let's look at performance over time.

The discrepancy between Titan and 290X naturally grows in a multi-card configuration, though the $550 board from AMD still has plenty to be proud of.

Enabling CrossFire over PCI Express through a DMA engine works brilliantly for circumventing the bottleneck imposed by AMD's top bridges. However, this mechanism might not be optimized yet. Our frame time variance numbers are by no means problematic. But they are notably higher than what Nvidia can do in SLI.

This is win-win-win for everyone (except maybe Nvidia).
Hope we never have to deal with a $1000 single GPU fiasco again. Good riddance.
- AMD: We're not aiming for the ultra high end.
I think Nvidia just got trolled.

Most of the higher resolution gaming wins come from the larger memory bandwidth and of course more vs the 780.
That's a good sign. Maybe NVidia will drop prices and push this to $400-$450 and I will pick one up when there is a Vapor-X version of course,
