What kind of setups do people have at home, enjoy, or recommend? As it will be primarily used on a short-to-medium-term basis, I'm looking for a setup that when all of this is over, will not go to waste.
I don't know if Intel will manage to blight innovation and keep the market static as they have the last decade, or if the "upgrade cycle" will begin to make sense again down the road.
Also: 4k monitors are worth the price. Pixels will make you happy.
Finally, I advise spending at least twice what you initially think necessary for the mouse, keyboard, etc ancillary interface stuff. People skimp on these and then spend years with a crappy keyboard and growing RSI. Buy the good monitor stand and the wide mouse mat or fancy trackball or whatever.
