Yeah xp will except the dual monitor setup. I do suggest getting the same size monitors though just speaking from experience makes it a little easier on the eyes since the fonts are the same size and all. Good thing about the dual monitor setup is you can keep stuff you fiddle with on one side and scroll through the other stuff on your second monitor. I keep logics internal mixer on one monitor at all times that way I don't have to flip through screen presets to turn down the snare or some sound that's to loud.
