I get your PC is probably out of date but your opinion doesnt have to be.
Theres a big reason all high end graphics and special effects are done on macs and its aint because its the cheapest, dodgiest do-it-yourself system.
Ironically your opinion is outdated.
Macs were the standard in creative industries for decades but its now less relevant than ever before. Many top post-production houses now have combinations of Mac's and PC's compared to the early 2000's when it was pretty much entirely mac based.
Also one of the main reasons they originally became the standard in creative industries was nothing to do with them outperforming PC's in terms of power etc, they simply had a reputation for stability and ease of use that PC's didn't due to the hardware inside being standardised. This resulted in lots of creative types who didn't get on with computers or tech adopting them over a PC.
Nowadays there really is nothing you can do on a Mac that can't be done on a PC. The choice of computer used in post-production studios is much more down to history and what software is required than because they are the super duper best computers in da world.
I own and use both daily btw.
