I've got a Dell XPS M1330 laptop which is already a couple of years old. I've already upgraded to 8GB of RAM and a SDD. Since I do all my development work (under Ubuntu) on this machine, I'd like to get more performance out of it. Currently, the bottleneck seems to be CPU.
The BIOS version (sudo dmidecode -s bios-version) is A15. Hwinfo says the CPU now is a
6.15.13 "Intel(R) Core(TM)2 Duo CPU T5550 @ 1.83GHz"
I know I'll probably have to look for an upgrade on eBay or similar, but I can handle the installation myself.
The question is: Which models of CPU can I use without changing motherboard or other big renovations ? More cores would be my priority. Or how can I find this out myself ?
