Right now, I am using a GTX570 but I am about to add a second one within the next week. Anybody else running multiple video cards in SLI configuration? Did you see much of an improvement?
I don't think that SLI will give you any advantage in Vegas. Can't hurt, but I don't think it will help. Please prove me wrong and I'll be upgrading all my editing PC's.
does your power supply have the capacity for the additional card?
I have a 1250 Watt Gold rated psu. So power will not be a problem. I'll be sure to let you know if I see any improvement... and there better be an improvement or I'll be pissed.
I checked with a tech guy where I buy my parts and he told me it wouldn't work. Instead of wasting money on an expensive video card, I got the scanner I truly needed (the old one died this week).
