Mb air vs mb pro for engineering student

[dejoka]

Hi,
Im going to buy a laptop for me, and im wondering between two:
Macbook air with 8 gb ram, i7 1.7-3.3 ghz, 128 ssd, nd external drive
Macbook pro with 8 gb ram, i5 2.6-3.1, 128 ssd
I will be using it for music, films, interner and autocad(through bootcamp probably)!
Can you help me which one should i get?
How big is difference between intel iris graphics and intel hd graphics 5000?
Will this laptops smoothly run autocad for small projects?
I also appreciate long life battery, and i want this laptop for many years.
Ps. I will use external monitor in house - most of time.
Ps.2 maybe you have some older macbooks that will beter suits for me?
Cya, thx for help
Poor student

I would go for the Retina MacBook Pro due to the better selection of ports, only a half pound heavier than the Air, and a Retina display. You may want to bump to the 15" if the dedicated GPU is important to you.
