It really needs to have intel quicksync as that’s the part that decodes the video smoothly. And I just checked and they all have it so any of them should be fine. The 4th gen clearly outputs 4k. The others are less clear on that ability.

I know a guy cold calling and made 3 million his first year in business for himself.

Just get a job until you find what you want to do.

You could get a maximum of 10mill from the sba to get a small business. They’ll give five for the business and five for the real estate. Most people end up making more on the real estate imo.
