What can I buy upgrading to a newer processor, motherboard & ram for the lower budget with Gigabyte and Intel company which may be perfect play for video editing Softwares and more? I want to buy 4th gen core I7 processor for existing motherboard. Do you think is it appropriate solution for me? I want a suggestion to everybody. Notably, I live in Bangladesh.
