I have found that new equipment burn-in is not linear. In other words, things can get worse, before they get better. Also, there may not be much change for a week, and then it changes every single day for the next week.
Unfortunately, this stuff needs 400 hours minimum before conclusions can be made. Otherwise, you are likely to be chasing your tail. Perhaps the best thing for sanity is to buy something and go on a vacation while it plays. Hey, at least you will have something to look forward to when you get back.
