Best value for a decent AMD system is not going to be coming from Amazon right now. Just want a single place to buy from, or does your friend already have money in an Amazon account?
Same build is a lot cheaper from various sources. Emphasis on CPU since rendering and video editing are important.

Not having much luck shaving more then a few dollars on Amazon. Their motherboard prices are particularly high compared to other vendors.
