It was something along the lines of going from one card to two increased power by 100% and going from two to three increased power by about 40%.
First, is this true and second, how do other leading cards compare in scaling?
Im sure it will all be ironed out, or make sure you stick to a specific manufacturer, for instance XFX or Gigabyte, both of which I feel offer the most reliable and more energy efficient cards.
XFX makes very solid cards i can testify to that. no issues whatsoever. i think i'll wait for about a month or a month and a half before i get the GF480 even though my 295's r running beautifully. one thing about the 480 that really bothers me is that it has a voracious appetite for power. i think its about 650W plus under full 3D load each.
You should have said performance instead of power >.<
Yeah it scales well when SLI'ing, its close to 100% per card.
Back to general talking now
ATI fans can say what they wish, but the 4xx GPU's can handle more in terms of texels, pixels etc which would bottleneck the 5970.
ATI have more threads (aka Streams) running at once than Nvidia cards, but Nvidia cards have better hardware that dont need threads as much to do certain things. For instance, CUDA effects, Physx effects and so on.
Eventually games will start using more and more Physx hardware usage, and thats when ATI will lose out.

XFX also has the best warranty of all manufacturers.
I ruined an XFX GeForce 7950 card installing an aftermarket cooler and they refunded me the retail price--even though I got it on sale and had a rebate, AND ruined it myself.
