I've never had a problem with different sized monitors on XP running together. At one point I had one XP machine with 3 monitors (19" standard @ 1152x864, 20" standard @ 1280x1024, 27" wide @ 1920x1200) and had no problems.
XP has a known issue with performance on dual view (more than 1 monitor not spanned by a video driver) where the 2nd/3rd/xth monitors take a huge framerate hit over the main display.

Since you can't Span a 1280x1024 monitor with a 1680x1050 monitor...
