The only reason we are arguing is a 192 bit card was a x060 class card before Nvidia pulled shenanigans by pushing a 192 bit class card into the x070 bracket.
The 4070 (and Ti) is fantastic from a power consumption perspective, but between being priced high and being low on VRAM (if the 3070 is anything to go by anyway), its an awful buy.
In Australia, the 4070 Ti has been creeping down in price, and because of that fantastic power usage, you should be encouraged to pick up the cheaper options rather than the hulking AIB's, as you just don't need that much to get good performance. Want even better power performance? The 4070 Ti even responds pretty well to dropping power limits without losing much.
Anyway, we all know AMD is a much more compelling option both used (6800/6900) or new (7800) in current pricing. Either buy that, or take your Nvidiaing with a pinch of lube and move on.
