I'm looking to get a either the HD7970 lightning (£200) or the 4Gb GTX680 classified (£230) over the next few days.
Shadowplay is important to me as I'm currently regularly using FRAPS (I don't like the file sizes/ performance hit). I play at 1440p (but only tend to record 1080p @60fps anyway).
I play BF3/4, Assassins Creed 3, Batman: AO, and Rome 2.
I'm leaning towards the 680, because of SP and the 4Gb frame buffer (for possible SLI down the road), slightly lower TDP, but I know the 7970 OC is a beast for just raw performance.
Any views, comments, things I've overlooked/missed? Thanks in advance.
My specs:
I5-3570, 8Gb HyperX 1866MHz, Corsair RM550
 
Solution
I would personally get the 680 just because of the 4GB of VRAM for SLI and ShadowPlay (if I was recording). Otherwise the cards are pretty much equal.
