The first time I opened an invite steam said I couldn’t join, but on a whim I opened it a week later and it worked. I still live in a different city so don’t know what happened.

I’ve been using my Sennheiser HD 598 s for over 10 years. I’d recommend anything the same shape/size: being large over ears means it doesn’t touch or squeeze your ears at all. Being open backed and velvet padded stop my ears getting hot and sweaty. Being wired saves weight, prevents lag/quality concerns and isn’t too big a deal in a stationary gaming situation.

I do need to use an external mic for chatting, which is not ideal if you’re gonna be always in voice chats when gaming. Dedicated gaming headsets tend to not sound as good for the same price, but can’t deny the convenience.

A lot of desktop motherboards have a slot for a M.2 WiFi card like that AX200. Usually though they already come with a card anyway. You can often also use the same ssd/HDDs going from laptop to desktop. CPU, RAM, and GPUs are different sizes and connectors though, and won’t be transferrable.

Main thing for choosing a mac is the personal preference for the OS / interface. Its not totally better than Windows, there’s pros and cons. You have to really want it to pay for the overpriced hardware. Even second hand they retain a lot resale value.
