Is this computer build good enough?

The computer i am building is going to be playing games and using 3D modeling software (solidworks).If you have a reason that i should change my options please explain. I feel like ive got this build down i just wanna run it by fellow enthusiast.

Big questions:
-i have been told i might want to invest in one more video card but from the specs i was looking off of on Nvidia's website i think ill be able to run the triple monitor setup(i know its 27in and 3D yes im crazy). Prove these other people wrong or sway me to buy the extra one.

-i cant choose between the 2nd gen Intel Core i7-3930K Sandy Bridge-E or the one i have picked out (down below) which do you guys will do. i know the 4th gen is faster but it only has 4 cores while the 2nd gen has 6 cores. i know ill have to change the motherboard and maybe the RAM if you guys think i should get the 2nd gen intel. itll be the rampage IV extreme if thats the case and then ill just find some G. Skills that fit that board

-last question will the power be sufficient
