Your experiences with TS2 and TSM are to be expected. They don't have anywhere near the impact on hardware that TS3 does.
They haven't manufactured GT(X) 700 series cards in ages, these cards are from at least 7-8 years ago. I was just using those model numbers as points of reference. Since then the 800 series (laptops only), the 900s, and the 1000s have come and gone. Although there may still be 1050s and higher on the market if the older stock is there, I feel like I still occasionally see new systems with 1060s and 1070s in them although that could be my imagination playing tricks on me.
The more modern series cards such as the 1600s and 2000s (yeah, these model series numbers are for the birds) are in very short supply and obnoxiously expensive as standalone components right now. I believe that has to do with increased demand and manufacturing difficulties during the worldwide pandemic. This too shall pass, but it doesn't make shopping for them very easy right now, at least from what I've heard. It looks to me like NewEgg, for example, still has 1060s in stock though not at what I would call bargain basement prices either.
