It will be fine for a couple of years or more- i'll be using a 4080 by the time i notice any issues. As i managed to pre-order from A..zon yesterday morning (not cancelled yet) i don't care as i'll be straight onto their CS and get a refund anyway. Or maybe i'll do that in a few months if i fancy it anyway
Couple of years on 1080P/1440P sounds very boring to me. You'd be better off with one of the new consoles, at least they are 4k.
10GB VRAM is not enough for 4K, even today.
