Is it a big deal now a days, given that pc's are faster than ever and can tolerate more "stuff" running in the background? Windows xp is pretty stable and does a good job. I am not a big game guy. I use my pc for Cubase/reason, web browseing, email, and the odd thing or 2 on ms word. Of course antivirus is used, but nothing Norton. Should I stay on one pc still and upgrade what I have or should I just build a new box for audio only?
