I wouldn't buy a Pascal GPU now, but I can see why some would. The reality is, people haven't just decided to buy a new graphics card. They've wanted one for months but couldn't get one. Now they can. Also, as cool as a new architecture would be, I don't think we need it. Pascal has been out for two years, but it's still going strong and showing no major signs of weakness. Any new architecture will likely just be a refinement by reducing the TDP and price (slightly). But yeah, seeing new stock likely means we're still many months away from anything from Turing/Volta/Ampere.
