transparent laptop skin? RM? where to get bro? 

I heard u like Assassin Creed. If u liek fiddling with drivers and spend some time to get the best out of your system.
- A43TA-VX047v, AMD A6-3400M + AMD HD6720G2@RM1899 <--- still got this model around?
will give you the best performance/price.

Pros:

• Can undervolt to lower temperature and increase battery life.
  
• Can overclock the CPU for more performance. (I'm not sure if the GPU is overclockable)
  
• Better discrete graphic compared to GT520M.
  

Cons:

• Crossfire driver support could be pain in the butt.
  
• No Crossfire support for DX9 game, so Assassin Creed is out. Only can use dGPU for that.
  
• PowerXpress need improvement. No indicator to show which GPU you are currently using.
  

I can't comment on the build quality since i never touch it.

If you don't like fiddling with the settings and drivers.. go for Marcus recommendation.
