My Grandparents bought a El Cheapo computer that is a utter piece of garbage. It has a Intel Celeron for christ sake. It runs like garbage and Amazon is currently selling Core 2 Duos for a massive 76% off at about $45. I was thinking up getting one to put in this PC to get it moving a bit. For what they use the computer for a Core 2 Duo would be plenty, but this Celeron is just running like garbage. Would a Core 2 Duo work fine in this computer? Also, how would I find out the exact specs of this PC like what motherboard it has. The PC in question is a Acer Aspire M1800. I have never upgrade a prebuilt so I'm asking here before I buy the CPU.
