A:AnswerHi!
Unfortunately we do not control the Best Buy sales, so you'd need to speak with them to get a better idea of how long the sale is running.
Thank you,

This system does not come with native wireless capabilities. It is fully compatible with wireless USB adapters, or can be hooked up via Ethernet.
Thanks,
A:AnswerThis PC does not come with a monitor, though it does come with a standard keyboard and mouse setup. It's not possible to buy these without the keyboard and mouse via Best Buy, as they come pre-packaged with the unit.
Thanks,
A:AnswerThomas,
It will depend entirely on what resolution and in-game settings you have. This system can definitely play Overwatch without lag, but the settings may need to be somewhere between medium-high.
Thank you,
