I actually contacted Nvidia yesterday on their online chat and specifically asked them this - even if the card is brand new and unopened and un registered they said the warranty could not be transferred - I am not too sure how legal that is but the bottom line is do not buy from someone scalping as there effectively is no warranty then.Depends on the vendor. Some do not recognise 2nd hand warranty at all (example is NVIDIA with FE cards - they specifically state that on their website), some other do not care or don't ask. Best to check particular vendor's terms of service about it or forums.
