CF was a no-go until last AMD driver, now it becomes an atractive solution for the few titles that you cant hit 60fps @ 1440p+. you can't use Cf for multimonitor gaming reliably. So 3x1080p is still NVIDIA turf, just remember that you can't mix and match monitors in surround. The only stable NVIDIA setup is 3 identicals monitors. CF, while not perfect is much more flexible.
But NVIDIA solution did not showed great numbers against AMD cards in 1600p and above; 760 is neck to neck with 7950 boost at 1440p, bt loses more often than wins at triple 1080p setups. Not that any card is viable for triple monitor gaming, as you will be running out graphics juice way before memory size becames an issue.
760 launch price was USD250, now expect to pay a bit more. if you wanna any game on the never settle bundle, it is a no brainer to go with AMD. Power is about the same, as is performance. 760 is a bit faster for low-end resolutions like 1080p, they tie at 1440p and 7950 "wins" by a large margin in 3x1080p, but you will not get playable frame rates there.
A fanoy stated above that AMD is about to launch next generation cards, so piking a 7950 now would put yopu on a last generation card. i say the reason to buy a new card is that you need it to play a game NOW. 760 is also a rebadge of an old generation card, so it pure fanboyism to argue that 760 is newer tech than 7950. if anything, a 7950 would last you longer: lower thermals and larger memory grants it least that.
If i would pick one card today, it would be a 7950 boost. if my gaming needs required more than a 7950, i would up the ante until a 780, not SLI a 760 or CF a 7950.
