Hey guys! My old XP desktop finally kicked the bucket, and I'm looking to replace it with a new laptop. I'd rather not spend more than $400, which I know is not a lot. What kind of limitations will I have? I've heard people on here talk about 5400 vs. 7200 Hard drives. Will a 5400 RPM not allow me to say, record 2-3 tracks at once in Cubase? Will Cubase 4 (LE, if that matters) still work with Windows 8? I have an external Audio interface (Lexicon Alpha) so do I need to worry about sound cards on a computer? Thanks for any help, and specific laptop recommendations would be great.
