Just wondering as to if 4gb vram is needed for SLIing GTX 760/770 if I'm going to be running a 3 monitor set up, the middle being ASUS VG278HE 1080p, and the two on either side being ASUS PB278Q 1440p or Qnix Q2710 1440p.

Cheers

Originally, I was going to go with a budget 4670k setup, but changed my mind and decided to sell my rMBP, adding $2000 to the pot.

I'm a bit of a Corsair/ASUS fan as you could tell, but I may switch up the H100i with a Swiftech H220...

I'm going to build this over a period of time so I'm waiting to see if 760 will be out with 3 or 4gb. Otherwise, I may just go with 770 4gb but will have to cut back on something else....
Going for an all SSD setup with a 3tb external drive.
