My advice is to watch for firesale deals from retailers during Black Friday if they are also anticipating SUPER cards to come into stock very soon and want to move inventory before then we'll see heavy discounts. Only the 5070 w/12GB of VRAM is really on the knife edge of being not worth it long-term @ 1440p, the vanilla 5070 Ti/5080 are well-equipped stock. If there's a really good sell (on those upper tier models especially) pulling the trigger early won't have you miss anything. If you're targeting something around $400-500 the 5070 Super will not only have more VRAM but extra CUDA cores for a performance boost there too.
