I would at least wait until WWDC which is only a month away—June 3rd.
It’s not impossible that Apple will reveal new pro solutions including both new monitors and the new Mac Pro.
I used to build PCs, back in the day but I am all in on MacOS now. I don’t “hate” Windows, but I certainly prefer MacOS and there is the aspect of having ONE eco system for phone, MacBook and Mac Pro.
I have a pimped out Mac Pro cheese grater that will carry me until the new Mac Pro is out. If the new computer becomes too expensive, I’ll reconsider my options.
A computer should be responsive and snappy. But raw performance isn’t everything. I just need to boot into Windows and spend 15 minutes there to immediately accept a 50% performance loss if I can only go back to Mac. Then again, if you’re basically just booting into one or two pro apps and then stay there (few interactions with the OS), then it won’t matter much what OS you’re on, as long as it shuts the hell up.
I’ve read many reports from Hackintoshers who have passed the honeymoon phase and later admit that it isn’t really worth it. They simply spend too much time on computer related stuff.
I used to like fiddling with the computer. I suspect many PC enthusiasts like it as well—like tweaking and optimising. But nowadays I want my workstation to be transparent and just get out of the way. My old Mac Pro never crashes of freezes despite rendering over weekends and such, That is worth a lot.
