Agreed. 3x tilted widescreens makes sense to me. You get clear vision in the center, and a slightly wider than normal aspect ratio. See the resi 5 screenshots in Anand's 5870 review.
For those worried about displayport on the 6x mini-displayport card, why not just use adapters?
3 or 5 tilted 24" monitors is my plan. Avoids the centre of the display being in a bezel, and gives both vertical and horizontal res boosts.
I'll probably go with BenQ FP241Ws with adapters if neccesary, as I already have one, the border is square with no fancy curves, and all the control...
