First post, tried to search for this, but didn't see it addressed in the FAQ. Basically, I would like to know what you get, and what you sacrifice, at the different price points? E.g. $500, $750, $1000. I am looking to build a new computer, biggest usage is for video editing, movies, PowerPoint creation. Before looking at components, I would like to know what budget would be realistic for what I want to do.
