30" vs 3x 23" in eyefinity (displays)

[BLindsay]

Ok so currently i have 3 dell U2311H's in eyefinity for a res of 5760x1080 and its really great in the games it works but the games it doesnt like Starcraft 2 im left stuck on 1 single 23" 1080p screen.

Sooo im thinking of trading out to the Dell 30" U3011 and maybe use 2 of my 23s just for extra desktop space (couldnt mix match them for gaming)

the 30" has a res of 2560x1600 for those not familiar with it so greater than 1080p even

It would be less strain on my video cards than the current 3 screens.

Thoughts? and im also curious if anyone has a 30" how blu-ray looks on it since it technically has to be streched to fit these monster screens
