I have a AMD Phenom II X6 1090T processor in my computer. I was going to just buy a new computer for video editing but according to passmark my processor is still pretty good after 5 years. It has 6 cores and still cost $399.00. Everything is above average on this computer except for the video card. It is a ATI Radeon HD 4600 Series. I purchased the Hitfilm editing software and it says to get a minimum AMD Radeon HD 5000 or better. Does anyone have any suggestions on what card might work well. I don't know much about AMD Video cards. Thank You.
