Depends on what you're planning to do with that said computer. It also depends on how much money you're willing to spend. If you're a gamer then I suggest you buy one with an Intel I5 processor. This processor is usually ideal for gaming. However if you plan on using it for something else other then gaming then you could do well with an I3 too. I don't know much about AMD processors so I can't really say anything about them. Personally I stopped using a PC 3 years ago when I sold my old junk and bought a Lenovo laptop. It works very well but unfortunately it has an Intel I3 so I struggle with some games, especially new ones like 2015 and forward. However I plan to change that.
