My current mac is dying, i'll need a new laptop for my work (as multimedia designer), pls recommend :-)

1. Preferred Brand: NONE, but definitely not mac with my budget
2. Budget: not more than 3.5k
3. Usage: high performance on heavy graphics,video rendering software eg: adobe cs6 softwares, dreamweaver, 3D, no gaming.
4. Preferred laptop/screen size: 14~15", lightweight and slim
5. At least quad core, is it possible to get with SSD if within my budget?
