I don't know a ton about PC builds, but I'm considering investing in a new one for professional video editing.
My budget's around $3,000 currently, and I'm looking for a computer powerful enough for smooth editing with a moderate level of special fx applied to projects that I'm working on in Premiere and After Effects. Being able to edit more plain stuff (e.g. with lower levels of fx) in 4k would be nice as well, but not required.
This page by Puget Systems seems like a good starting point to base my hardware around -- what are your opinions on the basic build they have laid out there?
