I've been using a DAW - p42ghz, 512mg ram, one 10gig harddrive, and another 80gig hardrive, running Cubase 3.7 with a Lexicon Core 2 interface. Well, I just bought a Delta 1010 for the added inputs and have the opportunity to upgrade to Windows 2000. I've previously experienced some problems with the system freezing up and the Lexicon has always had conflict problems with the installed soundblaster card. Should I upgrade, or just install the new interface? Any thoughts would be appreciated. Thanks!
