I'm trying to get my parents to buy a new computer and I'll mainly be using it for CAD, but a little for gaming also. I can't spend more than $1100 or so, so I'm going to have to decide what to upgrade and what not to. So with that in mind, what do you think I should upgrade? Processor? Memory? Video Card? I'm definitely upgrading the Memory becuase I know a lot of CAD programs I use in school are memory hogs. I'm not so sure about upgrading the video card or processor. Do you have any suggestions?
