GTX 770 or 970?

I currently have a GTX 770 2gb, is it worth spending the money on a 970 as an upgrade? The specific cards are linked below.

If you're at 1080p just stick with the GTX 770, unless you're playing something like Skyrim with a bajillion graphic mods.

Spec wise there's not much of a difference other than TDP and amount of RAM.

Erm, maybe I'm misunderstanding you here but "Spec wise there's not much of a difference other than TDP and amount of RAM." is complete bollocks. It's a different architecture, you can't just compare specs. In actual gaming the 970 is way ahead of the 770. It even beats the R9 290 at 1080p in many games.
