No, it's not.
People that uses cards in the professional sector buys the professional cards from NVIDIA,
GeForce cards are meant for gaming
There are still some prosumers (not professionals) that wants a GeForce card to make prosumer tasks but that is a very very very small nichy,
your story does not represent the truth.
I try to explain my point of view.
You printed 10 waterblocks just to have the first 10 customers act as beta testers, as any large-scale problems would have caused economic damage.
If the first 10 beta testers do not complain, you will gradually increase production, but you obviously do not want to stockpile or advance too much money, and this is why you opened preorders.
You print waterblocks only after receiving the customers' money, no risk for you, no inventory expenses.
This is the reality, or at least, the only credible one in this discussion.
In any case I think that there is no reasons to continue this discussion becasue our opinion is not going to change further.
