I'd like to build a PC for video editing and gaming i have a budget of £800-£900 i would like to stay to the lower end of this range. If I can edit 4k that would be great if not 1080p is fine. Can someone give me any suggestions for parts please?
Thanks for any advice people can give.
Edit:I have a monitor, operating system, speaker, keyboard and mouse
Edit 2: I will mainly be using Davinci Resolve
