This PC does not have a wireless adapter built-in. To get wireless capability, any USB WiFi adapter will work. You can also purchase any PCI WiFi adapter. There is an available PCI-Express x1 slot on the motherboard but depending on which graphics card is installed, this may or may not be accessible so we can't recommend getting a PCI-Express wireless adapter. We recommend getting an adapter with technology equal or better to what your home's wireless router has. So for example if your router has 802.11n connectivity, you should get an adapter that also has 802.11n connectivity or better (802.11ac).

This pc feature the intel HD4600 graphics chip which is integrated into the Intel Core i3-4330 processor. While this is a capable graphics chip, it is not well-suited for more graphically intensive games like DayZ or similar, modern FPS/action games. We recommend going with a system configuration that has a more powerful discrete graphics card, something on the level of the NVIDIA GeForce GTX 750 Ti or AMD Radeon R7-265 (in that general ballpark). If you have more specific questions for us, please don't hesitate to call our sales department at (800)707-0393

This system can run Sims 3 and 4, but we recommend going with a system that offers a discrete graphics card such as the NVIDIA GeForce GTX series or AMD Radeon R7 or R9 series, as that will offer better performance which will let you enable higher quality settings and have an overall better gaming experience.
