I have roughly $1800 to spend on a computer. I have decided to go with the XPS but am unsure what model to get. The computer will be used for creative purpose only. Meaning for graphic interface like: 3ds, Maya, Photoshop… So, if you know a lot about computer I would great appreciate the help in finding the best computer that will fit my needs. Also, what operating system is the best to be running right now?
