Those who pre-ordered the RTX 2080 Ti FE with an original ship date in October can expect a shipment by October 10, 2018. General availability will probably follow soon.
NVIDIA apologizes for the delay, and claims its supply chain challenges are now resolved:
Our supply chain challenges are resolved, and we will have cards in your hands as soon as possible. We sincerely apologize for the inconvenience this delay has caused you. We aim to deliver a great customer experience, and we recognize this has been a disappointment.
