I would probably go with the Athlon x4 750k or 760K. If I remember correctly its basically the same thing as the A10-6800k minus the integrated graphics. That should save you some money to use for the 280x or PSU
I used to have it on for everything because the ads annoyed me. Now I have filters for twitch and youtube because hey its free content and 10-15 seconds isn't too bad. Feels good supporting certain people
