What laptop specs for better performance?

Hi,

I'm using Edge CC 2014,

I have always seen a "lag" in some actions, like when double click to open a symbol, it takes 3 seconds, or zoom in /out takes 0.5 second.

I thought it was normal on Edge, but a friend started using Edge and in his Mac is double faster, it has the same processor, memory and video chip.

Mine is an ASUS Q500A  i7 quad-core, 8 RAM, Intel video 4000, Windows 8.1

please help.  Could you suggest what laptop specs would give Edge better performance during development?.  Edge would use a video card GPU during developmen?

thanks in advance,

Paul
