Most definitely, if you’re going to torture test your machine with big files, and LONG rendering sessions—I think it’s better to be running those projects on a PC. (… and ideally on a rendering farm).
Apple’s just not up to the task… You’ll be limited in the hardware specs which are available to you for the price you mentioned, and that would probably still be true at double (…and triple) the cost.
But, what’s more worrisome are the issues with overheating which I think you’ll encounter… Apple’s obsession with thin products has come at the expense of having a compromised and weak cooling system.
Having said all that, you can certainly test drive whatever computer you buy from Apple. Maybe your thresholds for safe operating temperatures are higher than mine. . . and in any event you can always return what you buy within the timeframe allowed.
