add the max ram for vista
you will have problems with xp on a computer built for vista
just wait for 7 to come out on the 22nd and get it.
You can install Windows XP on the new computer using the Windows XP original installation disk. You will have to format the C drive and install Windows XP fresh as you cannot downgrade to Windows XP from Vista. Windows 7 seems to be much better OS than Vista and XP and hence as someone pointed out already here, its a good idea to wait for a while and upgrade to Vista directly.
