Moore's law stated that the number of transistors / performance doubles every 18 months. Over 3 years, the new machine will be 4 times as fast as the 3 year old one and that's assumoing you bought the $1,000 CPU and the $400 MoBo. At 6 years, that's 16 times as fast. My 1st PC build was in the mid 1980's....my 1st Wintel in 1993. Since then, the machine "you want" seems to always always costs $3,000. Comparing todays $3k PC w/ 1993's I can say that today, from a disposable income standpoint, we are getting a much better deal than we did back then.
