Now I know that some laptops you cant change the processor and all that but does anyone know how I can know if my laptop can let me change my processor and I have an intel core i5-421OU 1.7 GHz with turbo boost up to 2.7 Ghz and I want to change to Intel Core i5-4590 BX80646I54590 Processor (6M Cache, 3.3 GHz) so my first question is, is the change from 2.7 Ghz to 3.3 GHz noticeable and is it worth it and is my laptop compatible with the other intel core i5 version. THX SO MUCH in advanced I'm new to computers and want to get not a serious gaming laptop just so I can run my steam games faster thx in advanced
