As much as I hate to say it, the move at this point is GeForce Now, at least for the time being... I just subscribed to the 200 USD/year Ultimate plan with a free 007 game. My ping to the datacenter is a mere 5ms, with 5080, RTX, 4k@60Hz (which my projector can drive) I am getting way more performance and similar latency than I would if I were using my own, semi-affordable rig or even a PS5. It's mind-blowing, really, and I recommend anyone to at least give it a try.
If I take out the cost of that 007 game, that plan i 140 USD a year. If you consider the cost of the electricity, it alone would likely cover it. In the past one would typically include hardware depreciation cost in such calculations to drive the point home...but the 3-4k USD I am not spending spending on a similar rig alone can generate me some 100-150 USD in bank over a year – not to mention the inflation! So, all in all, it's basically free, comparatively speaking.
