Well more specifically in BF3 the performance is a huge difference between the 680 and 7970. The 680 slightly outperforms the 7970 in the majority of games, although in bf3 the 680 pulls far ahead than the 7970 in bf3. This card would run 3 monitors with bf3 running fairly well. When it comes to high res, vram is your friend. the 4gb on that card is more than enough. Although the card will be running quiet warm so be prepared for that.
there is a reason why 7970 out performs over the nvidia and no im not going into detail cause youll just reply im wrong either way
and edit: personal experience and ownership of a Kepler card, 680 should run cooler then a 560 by almost 20c on average and with the card i linked he should never have heating issues if the case air flow is good (the 560 example is because that card ran very hot like the 480s)
