I’m personally not touching the Pimax ‘8K’ with a barge pole. There’s too much smoke and mirrors involved for my liking. They’re not 8K headsets, they’re 4K headsets. The screens are looking like they’re running at 75Hz too. All we’ve seen so far are 3 prototypes so things may change by the time it releases but I’m personally not too sure whether they’ll end up delivering on all of their promises on launch day and even if they do I can see their launch being delayed too.
You’ll be better off going for the Rift and Touch bundle imo.
