But it's retarded. IF i legit bought Zotac card for example and lost my invoice or something, i am not able to claim warranty. That sux...
I would agree with you on that point and you would probably be able to make a claim if you persisted hard enough. But on the other hand why wouldn't you have an invoice if you as you say legitimately bought the card from an authorized re-seller? At the least, they could send you a new copy so you could receive service.
if i have a card and that card is faulty factory should replace it regardless. It's their obligation to make sure card works for 3 years after it's been produced... doesnt matter if i have invoice or not lolz xD
This is totally disagree with you on. They are under no obligation to honor a warranty for cards that are not sold through authorized channels.
Say for instance they manufactured a batch of cards that didn't pass their QA testing for some reasons, and maybe they have a contract with a recycling company to buy the defective cards from them at a bit less than cost and the other company makes its money by reclaiming the components. Now that other company goes through and tests each card before the reclaiming process, and maybe they are a bit unscrupulous. They may set cards aside that might fire up and kinda run, and then sell these at a discount (compared to normal wholesale) to another shady re-seller, who turns around and sells them to someone like you for a discount. Of course no one can offer an invoice as the whole thing is shady as hell but they do lure in some people who think getting a 40-50% discount on a brand new card is somehow legit.
Well now then we have a card that the manufacturer thought was disposed of turning back up to be serviced from a scammed customer. So how is that their responsibility to fix?
Of course this is just one of hundreds of possible scenarios of how you came to posses your card, but the point is if the seller is not willing to provide documentation or a invoice with a valid serial number to obtain warranty, you should be looking to shop elsewhere. You bought the card at a discount knowing that it could be an gamble, and now that you have lost that bet you want the manufacturer to come to the rescue. Sorry to say, but with that attitude you seem to be not a lot better than the scammers who took advantage of you in the first place.
