You sirs are the people with most common sense that i found in the internet, ever… i totally agree by the way, the performances were cheesy, the direction was cheesy, the photography was cheesy. I guess we can really call Rami, Mr. Robot. :)
I would buy a mac, especially because OS X El Capitan is coming in a couple of months and will introduce Metal, which is a technology that will improve rendering performance up to 8x and is supported by adobe apps.
I know that finding a 2012 or later macbook pro under 800$ might be difficult but not impossible and would be worth it in my opinion.
A mid 2012 15" rmbp with a dedicated nvidia graphics card and at least 8gb ram would be the ideal because you would be taking advantage of cuda too. Oh, and the retina screen won't hurt for sure!;)
I hope I helped.
