Macs break down just as much as PCs do, hardware wise. This is because the parts in macs aren't made by god, they are the from the same manafacturers that make PC components, like Intel and AMD. They don't make them out of gold on seperate factories for the Macs xD
If you do a 15 minute research, you will find out about the compatibility of your PC compnents. It's not hard.
And talking about software incompatibility, just the name Mac should be enough. Luckily they are starting to fix it a little bit but it's still awful
