The GTX770 would indeed struggle to drive 3x 1440p @ 60hz displays.
To achieve 144hz on a 1440p display the display must be connected to the GPU via Display-Port, using a total of 12.74GB/s of the 17.28GB/s available bandwidth of a single DP1.2 cable, so to achieve 3x 1440p @ 144hz you would require a GPU with 3x DP1.2 outputs.
1440p @60hz is manageable over DualLink-DVI and HDMIv1.3+.
Personally I would likely opt for the 3rd option:-

A 3x Config with the new Acer Predator 1440p IPS display flanked by 2 Asus PB278q's hopefully the colours would be similar and a slight difference wont matter too much as they will be peripheral vision monitors anyway
As for Nvidia vs AMD configuration and profiles, it is true that AMD does have the ability to create a number of profiles in all sorts of configurations.
Something I have previously done is to replace a games desktop shortcut for that of a .bat batch file that when clicked would change the display configuration from 3 extended displays into 1 large display spanned across all 3 monitors, launch the game and play at 5760x1080 then when the game closes, it would then automaticly switch back to 3x extended displays, thus allowing me to only enable eyefinity in different configurations per game, as and when I launched a game.
First I use AMD CCC to create a bunch of profiles, some eyefinity with bezel correction, some eyefinity without bezel correction, some smaller dual monitor eyefinity configs and the standard extended display mode.
Then using the commands below it is easy to switch back and forth between various different configurations on a per game basis.
Example:-
Code:
@ECHO OFF
ECHO Switching profiles and loading game, please wait . . .
"C:\Program Files (x86)\ATI Technologies\ATI.ACE\Core-Static\CLI.exe" Start Load profilename="span"
"C:\users\delphium\desktop\game.lnk"
ECHO Restoring profiles, please wait . . .
"C:\Program Files (x86)\ATI Technologies\ATI.ACE\Core-Static\CLI.exe" Start Load profilename="extend"
ping 1.1.1.1 -n 1 -w 6000 > NULL
"C:\Program Files (x86)\ATI Technologies\ATI.ACE\Core-Static\CLI.exe" Start Load profilename="extend"
EXIT
This switches to a spanned configuration, loads the game, when the game closes, it continues to the next line and reset the profiles back to extended mode.
Previously when using the profiles, the profiles sometimes restored back to a non 100% correct position, running the profile again a 2nd time seemed to clear this up.
