I think the e2200 is one of the first dual core pentiums that dell sold. What is the operating speed ? It would probably work ok but I prefer to have to much computer than run into problems in the future with not enough. What kind of system are you trading with now ? I personally would go with at least a 3 ghz quad core with min 4 gb of ram but 8 gb is even better, The quad core has a fsb of 1333 where as the dual core will be 800 at most. The box will run you about 1000 - 1200 built through dell with extended warranty without a monitor.
