Which Card video editing 3 monitors

[Photoscubaman]

HI There First post so be gentle.

I have a 3 monitor set up on ati 5970, alien area51 alx.

Have bought premier pro cs5, so need cuda for hardware rendering.

question is do i go for a twin sli set up 580 3gb version, to make 6gb vid ram.

or a single gtx590 setup, i beleive they have 3 monitor setup.

have 1200 wat power supply, i7 960 12gb 1600ram running at 3.8ghz at moment

I dont really know if i need the video ram.

i just know that i cant use a single 580 as i need 3 monitors.

think i might go for 590 as i can always put another one in later if needed.

really strugling to find stock for the Palit GTX 580 3GB DDR.

have sold one of my 5970's to pay for this, just need to be able to get my hands on the 580 or 590 bedfore i can pull the other one out to sell.

I do game a little, just use my buisness to justify some of the toys

I beleive the gaming cards offer a lot more for the money.
