Requirements
Now I have owned this since this past February and it turns out that my existing computer doesn't agree with it because of the mismatched performance so what is the best and most affordable computer/laptop that I should buy for this?
In the long run you're better off building your own PC than buying a premade PC. better value on parts, plus the ability to upgrade down the line. you could build something quality with as little as $500 and it shouldn't have any problems running the HD60 software. Me personally I have an i5-4690 processor and it runs without flaw. using the Stream function becomes a bit of an issue, but I use 3rd party software (OBS) thats more suited to handle those features.
