I was thinking about beefing up my laptop's RAM to 4GB as it doesn't run the best with Vista and 2GB, but sadly I am already maxed out at 2GB. I am thinking about upgrading the processor from a Celeron 540 (1.86 Ghz) to a C2D. I found one that matches the socket, but I have to do further research to see if the motherboard can support it.
