Xp advice

Hello me again ;D
I've currently got FS2002 under Win98, with a dual Piii 400 Mbytes(except Win98 can't utilise the other Piii). It runs pretty well but starts to lag a bit when I'm on the ground with buildings all around.
I'm presently putting together another puter with an Amd2000xp and 256DDR400Mhz under the hood
once I pulled one of the hard drives from the main puter I'll stick Xp on it and fire up FS2002.
Before I get to the finish line, does anyone know of any problems I may hit with Xp?
Cheers
