Well, the 480 did not scale well in resolution against the ATI model. The higher the video resolution, the faster the 480 dropped in performance against the ATI card.
Three of them? I hope you have a really good set of earplugs (3 cards @ 70dB each is uh,..loud), a really open case with lots of fans, and a 1500W power supply. For the 5 minutes they will run before dialing back thier performance due to heat, it might be neat. Unless you have some type of refrigerated case in mind?
If you really are hellbent on buying an NVidia product, I really think it would be smarter to wait until they do a refresh of the parts before touching them. This generation is wrought with physical design problems I am sure they will cure in the next 3 to 6 months, but it is your money.
I just do not see these cards as an option for anyone due to the heat, noise, power consumption, lack of overall performance gains, and costs. That is putting aside the design issues.
From my perspective, I see a support nightmare coming at me.
"Is there a way to turn up the VOX? I cannot hear it over the video card!"
"Your game melted my video card!"
"Why is my frame rate dropping after I have been playing for a 30 minutes?"
And so on, and so forth.
