Leon,
Look at your MB future compatibility with the expected chipsets releases. I would suggest getting a board that will survive you at least two future chipset releases. The manufactures work together and the information should be easy to find. (buy chip upgrades when they're superseded and going out cheap)
As for dreams, price your dreams today and buy them in about 8-12months at 40% off. Stay behind the cutting edge and it can be a lot cheaper.

Seconds can be good if you check gummie, not a bad one in your area. You might be able to get a good rig 2nd hand locally.
Market option, not a suggestion.

One thing about a mid end or better PC, you can AP edit quickly, edit family videos/photos, use video addons (Star Wars has a good addon, great for kids to make movies with), VR etc.
