Alright so I am trying to help out a buddy who has the computer above. However the computers slow 1.8ghz dual core is maxxing out at 1 chrome tab, and is too laggy for playing any games at all. I had read on intels site that the chipset supports a core 2 quad q6600, but from reading an article on the dell forums it sounds like in order to use the core 2 quads, you have to have the mobo that supports the kentsfield, while the one for his computer is conroe. I was wondering if there was a way to make a core 2 quad work in this setup or if we would have to purchase a new mobo and processor. I understand its an older machine, however our budget really cant afford more that $50 at this time. i was eyeing a core 2 quad q6600 on ebay for about $20
