A:AnswerYou will need discs to install the previous windows programs, otherwise everything should be OK. If you have a system earlier than windows 7 you should upgrade since there is no more support.
A:AnswerIf your asking what the Operating system is, it’s Windows 10 Home 64-Bit. The resolution depends on what monitor your using. Most modern monitors are 1080p, but there’s also 1440p and 4K which is what newer televisions have nowadays. I recommend 1080p on this desktop.
A:AnswerWell you could buy another 8 GB stick of 2400 MHz DDR4 RAM with an inflated price from Dell or you could buy a faster 2666 MHz pack of 2x8 GB DDR4 RAM from Corsair’s Vengeance lineup, it will perform faster but it will cost more than just an 8 GB stick of Dell RAM.
