A:AnswerI have mine connected to a crappy 32" Roku tv, so I can use it as additional desktop or as a tv and it works well, so I am rather certain you will enjoy your monitor with it.
A:AnswerYou should be given an option to apply for a best buy card when you purchase it. If you do that and if they give you a high enough credit limit to cover the entire cost of the computer you should be given 12 months no interest. Since it's a credit card, not a loan, you don't have to pay it off within 12 months. If you have a balance remaining after 12 months that's when they will start charging interest. If you already have a best buy card and you have a high enough limit you should be able to just put it on the card and be given the same option for 12 months interest free. Just make sure to ask about that when you're there and they should be able to answer any other questions you have about it.
A:AnswerI also purchased this model and my receipt also states in the description of i7 8700. I have yet to check the BIOs but Bestbuy will have to confirm if this is a typo or this Element E889 model is indeed a 8700 either way.
I'm also looking forward to your answer.
A:AnswerIt depends on what game you play and what platform the game is on, ie steam, origin, battle.net ect. A lot of games have controller support but there are still quite a few that don't.
As far as the PC itself you shouldn't have any issues using a PS4 controller on it. I use one on mine and just plug a cable into the controller and one of the the USB ports on the back and it works just fine.
