I had XP. I upgraded to iMac and have not been sorry. It is a more stable unit.
Whether you do that or go to Windows 7 is personal choice. With the current software changes, I suggest upgrade. Newer units can be spec to you. I usually try to see what software I want on each one, then look at the chip performance, followed by hardware choices.
Older machines cannot handle a lot of the newer software. So be sure you get enough Ram as well as memory for everything. Then review and perhaps add a bit more ram.
