Need New Laptop, but which one?

I use 2d/3d high graphic software for my art and I need a new laptop. I am currently using an alienware Area51m15x book and the guts are decent but the exterior is falling apart (as it's a known problem with this model). I'd go for another alienware but from personal experience, they are increadably overpriced. Other people suggest mac books but I can't stand mac's software. I just need a laptop with great graphics card, decent ram and a good processor that wont fall apart on me and last me more than 2 years. Any help?
