Bought this as a game room desktop for my son.This is a great refurbished system (so far). Came equipped with W10 Pro and immediately booted and updated the extras I installed.The installed video driver is ok for normal surfing, but I ended up adding a ZOTAC GeForce GT 710 2GB DDR3 PCI-E2.0 DL-DVI VGA HDMI Passive Cooled Single Slot Low Profile Graphics Card ($42.99) and a OURLINK 600Mbps AC600 Dual Band USB WiFi Dongle & Wireless Network Adapter ($14.98).  I matched this with a Dell 23" LED monitor I got on sale from Best Buy for $99. So, for about $300, my son has a nice gaming set-up and a historically reliable business desktop - (Dell excels with the build quality of their business systems).  He is onto Steam and playing all his FPS games and in heaven!Definitely a worth buying system!
