Should I buy a Macbook Pro Laptop?

Recently my father and I have discussed purchasing a apple macbook pro laptop instead of a Lenovo (which I thought I was getting). I know there are a lot of similarities and differences but I really just need some input.
I will be studying fashion design in college and I know I will be using a lot of software (jUST design floor had 3 mac labs! 3!)
I asked my friend who works at Best Buy and he thought Lenovo or Mac would be good, but if I was to get a Mac to get a MacBook Pro. I know the price differences are huge so this is hard for me
I need some help

Can I play a 6gb ram game with a 4gb ram pc?

I planned to buy assassin's creed unity, and when I checked the minimum requirement of the specs of the game it need 6gb ram, but I only have 4gb ram. Can I play it smoothly?
My pc is Lenovo laptop windows 8.0,
Intel Core i5-3230M CPU @ 2.60GHz,
4gb ram with 3.86gb usable
64-bit operating system, x64-based processor
Nvidia GeForce GT 740M version 311.27
no game card

I can play games like black ops2 and battlefield 3 just sometimes will have some glitch. So I wonder if Assassin's Creed can work on my pc.

How to calibrate a monitor on laptop?

Ok I'm a bit furious about this because this is not a new issue.

Problem 1: I need to calibrate it. Windows is offering a solution - that "questionaire" or what it's called, but it's relying on BUTTONS ON MONITOR.

I have no buttons on monitor. I can't change any values on the monitor.

Problem 2: even with basic things like the contrast, that I actually can change with the windows calibrating thingy, it looks like my screen is "Stuck" meaning, I change it, it stays changed for a second or two and then switches back to looking like before. Even when I push the contrast bar somwehere else and hit OK, the screen looks the same and when I start the calibration again it is set on the same numbers as before

so I have no idea how can I calibrate it, what do you suggest?

Added (1). I have a Lenovo G580, win7, graphics card: NVIDIA GeForce GT 635M. (I don't know where to find the other stuff) I update the driver for graphics card frequently, everytime an update pops up (there's a program along with it, with alerts)

on the site of Lenovo there's no relevant driver for my laptop to this problem

As I said, I use a calibration system Win provides, it's a form of questionaire where you can adjust the values during those steps. Which doent work, immediately switches back.
