Earlier quoted context omitted.
The 2008-2017 period was great for PC gaming. Now graphics cards alone cost as much or more than an entire console. The prices only seem to go up. Game streaming has the opportunity to dramatically decrease costs. I think it will work.
You don't need to buy a high-end graphics card. Those are for hobbyists who enjoy buying the latest kit and fitting water coolers etc. for its own sake. 17" Dell with a GeForce mobile whatever-it-comes-with will let you play everything fine for 5ish years if you're into the latest shooters, longer for other genres.
Now compare it to the cost of a streaming box & subscription.
