"CPU-burn has recently sat down and taken a good hard look at what all is available on the market currently, what is going to be arriving on local shelves in the very near future, and has decided to write up a quick buyers guide for 3 types of systems. The Ultimate Machine is a no holds barred, money's no object computer system containing the latest products and some which will be released very soon. The Workstation is a system designed to stay under $2000 for the whole package while still providing near top of the line performance and contains only available products. The Budget System is designed to stay under the $1000 mark and serves the needs of people who seek this type of system; again this system contains only available products."
