GTX 770 or HD 7970 ?
I would recommend a 7970, it's as fast as a 680 & faster once both are overclocked.
It also has a significant edge over the 680/770 in higher resolutions & multi monitor setups.
There are 3 models which I feel comfortable recommending, the HIS 7970 IceQ X2, the Sapphire Dual-X & the MSI Twinfrozr III.
The Gigabyte & XFX models are voltage locked so avoid those.

The 7970 also has more VRAM than the 670 (7950 3GB, 680/770 2GB) & a significantly wider memory interface (7970 384bit, 770 254bit) this profoundly affects performance with Anti Aliasing (the graphics setting which removes jagged edges) and gives the card an edge on higher resolutions (the higher you go the larger the performance gap).

Another reason why I'd recommend the 7970 is that you get 4 games for free bundled with the card, Crysis 3, Bioshock Infinite, Tomb Raider & Far Cry 3 Blood Dragon.
This sums up what I think of the 770 as compared to the 7970:

I really don't think so, from what I've seen from all the reviews, the 7970 remains the better option unless you're a hardcore Nvidia fan.
The 7970 and the 770 perform within margin of error most of the time, except in games where the 7970 has a sizable advantage due to its double percision 64bit floating point performance like Hitman Absolution & Sleeping Dogs.
The 7970 also comes as standard with 3GB of VRAM so you don't find yourself in a situation like you do with the 770 where you have to think about whether you need to pony up for the larger 4GB buffer or stick to the standard 2GB.Another bonus is having the assurance that most if not all next-gen titles will be automatically optimized for your card because of the GCN based Radeon heart in the XBOX One & the PS4.
AMD also tries to swing you their way by their extremely attractive game bundle of Crysis 3, Tomb Raider, Bioshock Infinite & Far Cry : Blood Dragon.
You also feel safe knowing that if you decide to upgrade your monitor & migrate to higher resolutions that performance will scale better than the 770 & you will have enough memory.
There are still some advantages to the 770 however like GPU based PhysX and currently frame pacing in SLI, this advantage however will soon become irreverent when AMD release their Heart Beat pacing technology.
CUDA used to be an advantage in premiere pro software but Adobe & AMD went ahead and released OpenCL support on the new Premiere Pro CC software.
All in all though, I still maintain the 7970 is the better overall package.
