GTX 560 TI or GTX 580 3gb or GTX 680 4gb for adobe cs5.5 and cs6

I really need help on what to choose. I use after effects and premiere pro cs 5.5 and cs 6 once stable, i dont play games.
I have been reading this article.

http://www.studio1productions.com/Articles/PremiereCS5.htm

for premier pro and havent seen any info for after effects.

I am choosing from 3 cards gtx 560 TI, gtx 580 3gb and gtx 680 4gb.

My mobo is rampage 3 extreme so it only support pcie 2.0 i have read from other forum that there is not much difference between pcie 2.0 and pcie 3.0.

Im really confused, if the difference is only seconds like lets say, i render

60 secs on gtx560 TI
58 secs on gtx580
55 secs on gtx680

then i'll just go with gtx560 TI and then just buy SSD. If there is a significant difference between those 3 and its really worth it to get the highest and latest GPU then
ill go for it.

Pls guru's i need your help, i only read people saying to get the latest for the sole reason that its the latest and have highest spec but not really helpful.

I just hope i can find more information or real time benchmark on different cards like the studio1productions did. Its so much helpful.
