Those seem like niche things to hold on to. A 5090 should work just fine under Linux, what feature do you use that isn’t supported? Also a 9070 XT is capable of doing ray tracing. You don’t always have to have the absolute most powerful card.
I don’t have an HDR monitor so can’t say how well it works in Linux, but you can survive without HDR. Is a better lighting contrast that big of a deal?
Is DSL not available in rural areas? That still uses the phone line and should be significantly faster. I don’t understand how people can still even use dial up, can a 56k modem load most websites in a reasonable time frame? I should try throttling my connection and seeing if it’s viable.
