Guys,
Thanks for the replies.
I'll wait for the 4GB HD5970s to come out and then make my decision. And, if I do go the NVidia route, I will do Tri-SLI as I want the top of the line. I will do QUAD if possible but I believe only 3 will work (?).
Regarding monitor setups, that's a great point. I currently have TWO 1920x1200 monitors (24" & 25.5"; Dell & Samsung respectively) but I plan to get a 30" 2560x1600 as well. The only issue is for Eyefinity or Nvidia's version of it would look somewhat weird with two smaller monitors and one monstrous 30" in the middle.
Ideally, I could sell the two smaller ones and get 3 30" monitors but I'm probably not going to do that in the near future.
And, is the Apple 30" the best one out there because it's an IPS panel? What is the best 30" monitor available?
Here is a benchmark video of Tri-SLI of the GTX 480:

Looks incredible (with his whole setup)
