I really don't understand that line of thinking when the theoretical cards you're dreaming of are at least 18 months away. If you feel you can get by just fine for a whole 18 months with a 4070, why do you want a 90-class card anyway? Do you not expect to have any important work to do in the next year and a half or something? I'm not trying to talk you into buying a 4090 by any means, but you either need that kind of power or you don't. If a 4070 isn't going to cut it for what you want to do, then I don't see how spending the next 18 months struggling with one is quite the cunning strategy you seem to believe it is. Not to mention that the 5000 series might be even more expensive. Would anybody be even slightly shocked if it was? At that point you've kicked the can down the road, spent £600, struggled with a **** card for 18 months and ended up way paying more for the privilege.
