replace mobile gpu

[new24]

hi guys, I want to replace my graphics card with a workstation one. Any suggestions? My laptop is HP Pavilion 15 - p083TX:
CPU: core i7 4510u
RAM: Huyndai electronics 4GB DDR3L-1600 & Crucial technology 8GB DDR3L-1600
GPU: gt 840m

Not possible on a laptop - it has to be a mobile type as in existing GT 840m (m = mobile).
