Reply to Help choosing a DJ Laptop!!

Whatsup guys, first post so be gentle!
Im in the market for a new laptop, first one actually.
I need something stable, capable of running Traktor as well as being efficient in Ableton and Reason, etc.
Ill also be using it for CAD, but thats off topic. The question at hand is just what laptop I am to get. Ive been really interested in HP Envy series for their dedicated cards, RAM, and i7 processor. But im not sure if theyre any good for DJing. Im not really into macbooks, so talking about them wont really sway me.
Heres a link to the PCs Ive been looking at, my budget is 900 ish
