Best Computer (Desktop or Laptop) to support CorelDraw

I am currently on my 4th laptop in 3 years and this one is already failing me.  I went from an HP to Dell then Alienware and now I am working on an MSI (best one yet) but it is slowing down a ton and I have only had it for about a year.  I spend 5-8 hours a day on CorelDraw and would love something that flies!  Any suggestions would be very helpful, I am open to a desktop or a laptop :)
