Hi! I decided to buy a new macbook and actually I'am hesitating between the new macbook pro 15" , prized at 1,999$ and the other one for 2,599$ Do you think that 8gb ram and Intel iris pro will be sufficient for my architectural/ graphic work? That means everyday use of Photoshop, Illustrator, Rhinoceros, AutoCad and Vmware to run windows for 3d studio max+ Vray renderings. Or it's better to invest another 600$ for the top version? I also hope to use the machine for at least 4- 5 years. and I will not use it for playing games What do you think? I will be glad for any help Ciao!
