r9 290 4gb vs gtx 770 4gb

[tacoshmaco89]

I haven't been able to find any benchmarks that compare the 290 to the evga 770 sc 4gb. I am on the fence over which one I should buy, because the prices are so similar. Supposedly, the 290 is supposed to have similar frame rates as the gtx 780, meaning that the 290 would be a better deal, but with the CF issues, and overheating, I don't know where to stand. With the 290, you can buy a better cooler, and it has more vram, but since I am planning on using them on a 5760x1080 setup, I do not know which one is better. Any feedback will help.
Thanks!

What power supply will you be using to power these cards? Please name the make and model, not just wattage.

The most concerning thing that I've seen in forums is that a GTX 770 just doesn't have the gpu power to take advantage of 4gb of vram, neither does a pair of 770's.
