So with 3 19 inch monitors and 1 22 inch i lag like hell. like 6fps. And i got a pretty decent setup so i think. dual core 6400 4gigs and 2 8800gt cards. Looks like its just gonna be 2 monitors, and back to best but lol.

When you put different instances of WoW on different monitors, your FPS will drop drastically. Try it, put all instances on one monitor, then move them to another monitor and it'll go down significantly.

i have found horizontal view to perform better then dual-view
