I have a 3-year-old Pentium 4 and I'm interested in upgrading to the Core 2 Extreme QX6700 (after the price drops later this month). I understand that to upgrade to that processor, I'll need a new motherboard and RAM as well. I don't have the know-how to attempt such major surgery on my own, but having Alienware install the upgraded components (which I would have to buy from them at marked-up prices) would cost an arm and a leg. My preference would be to buy the individual components for the best price I can find on the Web, then take my system to a skilled computer technician for the installation. Are there places that will do this sort of thing? Geek Squad doesn't appear to be equipped to handle a major overhaul like this. Where can I find a place that will install computer parts purchased elsewhere? I would also need advice with purchasing the components, to make sure everything's compatible.
