ya you can get a great system for $2000 everything included.
do you want to build the computer yourself? that will be the BEST option for best value. its not a big deal, must read a couple of guides, and read some manuals.. piece of cake
where in canada do you live? do you want to buy parts from a local store? or do you want to buy parts from an out-of-province store and save the PST? there are pros and cons to both.
do you have a computer store in mind that you want to do business with? or just anyone with the best prices?
do you also want an operating system?
edit: since this is a high-end system, i recommend you await the release of conroe and decide on your build afterwards. if you like conroe, you can go that route, or if you don't, you'll be able to take advantage of AMD's lowered prices. you can do research and stuff in the mean time, i believe less than 2 weeks until the launch of conroe. so no big wait.
