I'm looking for a fast computer for video editing and live streaming. What are the parameters that I need? Thanks

All Macs less than 3 years old are robust enough to handle the vast majority of video editing requirements – including UHD resolution, native formats, and multi-cam projects, If it fits your budget, spring for maximum RAM and best graphics card available. (In many of the current models, upgrading those after purchase is not an option.)

Good luck.
