I have a HP 733 Celeron and will be buying a new computer within the next week or so. I only have around $1400.00 to spend max. What would be a good choice to run my music files without any problems. I'm working on a solo project and normally use a bunch of tracks mostly keyboard and guitar, just a couple of electronic drum tracks. I was thinking maybe 80 GB hard drive, how much SDRAM would be good, P4 machine? 
What is the most important thing to cover to get good performance?
Thanks,
