so, i'm in the process of building an offline-only windows-based pc solely for music creation. i'm trying to decide if it's worth going the w7 64-bit route, or if xp 64-bit would be fine.
i know that xp's 64-bit distro was really buggy, but it's also incredibly lightweight - under 200mb at any given time. it also runs anything created for music, ever - i've got several VSTs that have never functioned properly on w7 (the steinberg virtual guitars, for example, don't install on w7). my main worry is that w7 is definitely what is being developed for, and i don't want to have to reinstall all this stuff down the line just because everything in a year or two starts requiring w7. but i don't know if i want to lost a gigabyte or more to the OS itself. with a 64-bit box i guess it won't matter as much, but it'd be nice to not worry about it.
what do you think? i've got a 64-bit copy of w7 sitting around, and it shouldn't be tough to get the copy of xp if i decide to go that route. basically i'm asking if anyone's got experience with xp 64-bit, and if they think that my fears about bugs and crashes are unwarranted.
