Gtx580 sli vs radeon 7970 for after effects

Hi guys first of all to those who want to know my setup here it is

kinda too lazy to type all the hardware well anyway my only issue is that i'd like to use 4 or more monitor when im using after effects 1 for my real time emails and chat, 2nd monitor is for browsing the video and for playback, 3rd is for the after effects, 4th would be for premier or vegas.

But gtx580 only supports 2 monitors :( so i plan to SLI, would i benefit from it?

radeon hd 7970 supports up to 6 monitor for 1 card, would their be any disadvantages aside from not having the CUDA?

i use after effects and other video editing softwares, im happy with gtx580 but i really need more monitor..

guys i need your suggestion and opinion.

  1. Which version of After Effects? 5.5 or 6? If the 5 version you will need Nvidia so the 580 if 6 you can use either. Also you will have 2 580 but dont SLI if you want to use 4 screens just run them independently. Not sure if adobe can use more than one card for acceleration if it cannot get like one 580 and one 550 or something that uses less power.. Also only very specific 7970 can use 6 monitors.. Oh I almost forgot the 670/680 can do 4 screens on one card go that rout.

  2. I'll be using it on cs5.5 and cs6 in the future as im just waiting for a stable version of cs6 probably 3 months from now before i jump to an upgrade.

    I wont be upgrading to 680/690 as its very expensive i have a bargain 580 that is worth almost just 40% of the actual price so i was thinking of buying it, and the 7970 is also bargain .. if im convinced on using 7970 ill be selling my 580 and buy 7970 instead or perhaps buy the 2nd 580..

    just to use 4 monitors. Regarding using 2 gpu independently would that be even possible without problems in the future?

    thanks for the help though i appreciate it. :)
