I want to use the computer for games and simple things primarily, but I also want to start doing more video editing, and I have a tendency to run a lot of applications at the same time. I want something that will last me a while. My current setup is about 1 1/2 years old Intel 440BX-2 PIII 600 MHZ 512 MB PC 100 ram Geforce DDR SCSI 160 HDs [This message has been edited by Z-Man1915 (edited 26 January 2001).]

I am thinking about getting a new computer, and I am considering waiting for AMD's 760mp board so I can run dual Athlons. I am also thinking about a dual PIII setup. What kind of perforamce increase could I expect to see, and what types of applications would benefit the most? I plan to run 2000 on it.
