This system has issues. Out of the box, worked fine. Since then, numerous issues with the memory and video card causing system shutdown and errors. It is supposed to be a gaming PC but it does lag. 4 stars is being generous. Tried to contact customer service and had alot of runaround. Any issues, and only choice is to send the whole unit back. Hard to do when you already installed tons of programs and licenses and need it for work daily...
