I am currently a student in need of a new computer. I am studying architecture so I will be running programs such as AutoCAD, Revit, Inventor and 3ds Max. At the same time I want to be able to play games. In total I only have about $1000 to spend. That includes computer, mouse, keyboard and monitor. I have no other parts that I can reuse. I also live in the United States. For the processor and memory I was thinking that the bare minimum would be a xeon e3 1231 and 16 gb of ram. I only say that because at school for a while we used i5's with only 8 gb of ram and it just wasn't enough until we upgraded to the xeons with 16gb of ram. Thanks for any suggestions
