I do not shill for Nvidia nor any other company. But from objective technical standpoints I do not see any reason, why a 5060 Ti 16GB should be a bad product or should age badly. So please explain it here to us, I'm curious for your arguments.
Too high consumer prices is another business and not part of this particular discussion, because the card won't age differently when prices change.
A 5060 Ti 12GB won't be a bad card either. It might run earlier into VRAM issues, but it is still a decent 1440p card and very nice for 1080p if priced adequately. For e.g. 399$ it will be miles better than a 4060 Ti 8GB at the same 399$ price tag. Saying anything different is only for flame wars, because I would say the very same if it would be an AMD or Intel card with the same technical characteristics. Sure, 16GB are better than 12GB. But 12GB are far better than 8GB. And the 12GB version will cost less and typically have a better price/performance ratio than the 16GB version, if VRAM is not the issue (which it will not in most cases). So you can choose: Typically better price/performance ratio with the 12GB version but at some point in the future earlier obsolescence due to overfilled VRAM (depending on your screen resolution). Or if you want to play safe on VRAM take the 16GB version.
But go on, you could convince me now with some constructive points and arguments besides of denouncing me as a Nvidia shill. So please go ahead.
