i got the OS from a friend .........XP is just as efficient............ this OS is a bit faster in 32M for me...around half a second hence why i made it a permanent PI OS and also the other thing is this win2003 OS allows me to do my wazza in an easier way which for some reason is borked on XP on which i have to do manual crap....
have a look at Gyrock 8M run with Asus board (which is a bit faster than Giga at similar settings) on ripping.org and see what i mean about XP efficiency
