If we believe the leaked specs to be true, the 4070 Super sits between 4070 and 4070ti. So I think it should be ok to buy a 4070ti. And seeing that pc studio website, only that particular Innoc3D variant is of lower price. So Probably they are trying to drop prices before others to clear stock; as per other leaks 4070ti and 4080 production is stopped and will be replaced by the Super. But you should try to wait for the real info if you can, if for some reason it's a really urgent requirement and causing issues with your work why wait?
