780Ti vs 780 SLI (2560x1600)

What say you TS forum? I own one 780 and can buy another for <$400. I can also buy a 780Ti and sell my 780. What do you guys think? Keep in mind my res is 2560X1600. Thank you

the 780 sli will be best. The difference between the 780 and 780ti is not near as much as the difference as a 780ti and 2 780.

if the games and software that will come out in the next years will be better optimized for SLI.... and things point to that... i think you should go with the SLI
