I have already zotac 750 ti and currently I cant play battlefield 4 on med or high setting with my i3-540 so I want to update my processor so tell me if I update to fx6300 then I will be able to play on med-high setting?
You cannot install the AMD FX6300 onto a motherboard that accepts Intel processors. You'd have to change out the motherboard and possibly re-purchase Windows as well.
