I am sorry you had such a rotten day, but boy, do I understand what you are talking about. I get frequent migraines (probably most of them are basically stress-related)..& not so many meltdowns, because I bottle everything up & eventually explode. Yesterday was a bad day, most certainly.
The downclock thingy and remaining silent to the negative comments of this guy and others, adding to this the typical doom and gloom of a long-time Xbox hater, it was all too much for me to bear with.
Consequently I called him a liar -he was outright lying, actually-, among other improprieties and I got subsequently banned for a while from the other forum I usually write -not anymore, I hope, I don't like the atmosphere there- because of that.
I'd never do that in normal, ideal conditions.
My biggest bit of advice would be something similar to that, to research your options and let people speak before deciding anything.
I made my plan. I am going to buy the Xbox One if there aren't downclocks --if so, no gaming anymore. Then, a couple of years afterwards, a PS4 filled with exclusives -and GT-, all the shiny shiny, glitter glitter, is very tempting as a secondary console.
Hope the plan goes through.
