Im thinking of building a pc but before that, I want to know if my laptop can replace its cpu so I can run a better processor. I'd rather spend a $200 on a cpu instead of starting from scratch. I have a Satellite C55-A5105 with an Intel Celeron N2820. I plan to use my laptop for retro gaming, such as emulator gaming. Some other small net-based games here and there but nothing to serious.
