Workstations and gaming don't go together very well as they use different gpus. For workstations, get a quadrino or amd firepro as they are better for rendering. For gaming, geforce gpus are used, ie the gtx range. My best suggestion is to look at the lenovo p range, hp zbook range or the dell precision range as they are designed for workstation.
Alternatively, you could look at barebone laptops like sagar and see if they have a workstation rage.
