I want to start working from home, but the company I want to work for requires Intel core i3+, Intel core M ( 6th generation +) or AMD A series 2GHZ + and I am running a old AMD E-450. Although I have had the computer long I hardly ever used it until March of this year so I really don't want to have to buy a new one when this one runs like it just came out of the box with all its original storage space and speed and everything else. So my question is, can I change my processor to one of the Intel Core series or the other AMD A series without going broke or paying what It would cost to just replace it? If so which would be better and provide more bang for your buck?
Thanks in advance for all you all's help.
