not that big really...
4850 = 450watt
4870 = 500watt
4850 crossfire 550watt
4870 crossfire 600watt
So probably 550 to 650watt PSU will be enough for this.
Hd 4870x2 Crossfire will probably need 750watt to 850watt PSU.
Not as much as GTX 280 three way SLI anyway.

Its kinda been already answered everywhere. If Nvidia is that desperate to get the performance crown again (or at least don't want to wait for next generation". They would attempt go for it. However 1 GTX 280 costs 650, 2 = $1300. The TDP would be 350watts+ and a tremendous amount of heat, which equals into a hot card and a very expensive and loud cooler, the die is huge so impossible to stick with one PCB like ATI so they have to go double PCB again for the third time, which just drives the cost up some more.
I doubt Nvidia will even consider it until they shrink it to the 55nm proccess, even then it looks bleak.
Another thing is, there will be very limited quanties if they make a GTX 280x2. sharing the low yields for GTX 280 and GTX 280x2 will screw them up. Another thing there is basically there is no market for cards $1000+. People might have bought 8800Ultras for 999 when they came out, but that price dropped fast to $600ish for it to make sense buying vs. the GTX, also its simply not worth it when the 8800Ultra has turned into the HD 4850 which plays pretty much all games maxed @ $200.Edited by darksideleader - 6/30/08 at 4:38pm
