In your list of programs, Illustrator and Photoshop are CPU/RAM intensive, 3d Max and Maya can use some good GPU (from memory). Not familiar with vray and rhino.
For all of them, you will benefit from a good screen.
So for 15 inches, can you use a Macbook Pro ? It will run windows no problem. It is "architecturally" well designed and the screen is very nice on those.
If not that, then some ASUS laptops have a nice screen, though they are not nearly as nice in design and execution.
You can also consider some Lenovo ThinkPads. The T series for example may be your cup of tea if you want that style of computer. They are as expensive as the Macbook Pros though.
