I prefer 1 good computer.

My setup is: 1 Computer with 2 screens. (Samsung SyncMaster 204b)

The resolution is 1600x1200 so i can put my main 1600x1200 mainscreen fullscreen, 4 alts 800x600 on 2nd 4 times.

Also with keyclone you can easely switch windows to full screen regions, this is not possible with multiple pcs.

I suggest you to take 4gb+ ram if your going to walk in dalaran/do AV

Kind regards,

Steven A.k.A. Totemuc
