Can't really expect too much from a RM1.5k notebook, but I guess these will be the best pick

I supposed you are using AutoCAD, Solidwork in your study. AutoCAD need good CPU. Solidwork need good CPU & GPU. (And you need 64bit OS)
To have better experience running Solidwork, try to go for as good a GPU you can find within your budget.

Buddy, RM1699 no W8, Ubuntu only
