Eventually I was thinking I'd like to run 3 monitors, so I have both the X1900 and the 7300 currently in my Mac Pro. Until then, though, I'm wondering if there's any performance difference between having both monitors on the X1900 and having the primary on the X1900 and the secondary on the 7300. Mostly this is in terms of Aperture performance, but I'm curious what the differences would be across a lot of apps.
