For speed in processing you will need to go to Windows 7 64 bit with loads of memory but my personal opinion of windows 7 64 bit is that it is a pain to use til you get through a couple of months learning curve and it won't run compiled basic programs which irks me because I have so many little utilities for astronomical calculations.
So if your computer comes with Windows 7 64 bit back it up, partition your HDD, put your XP in a partition and then install Windows 7 from XP as a new system using someone's disk ( all you neded is the start up part to get your new menu) then overwrite the partition with your backed up image. (you can't install XP if windows 7 is already on the computer)
Next install VMware in your Windows 7 and you can have virtual copies of any operating system you like.
