@Shroud Pretty much reflected my thoughts.
The current gen GPU prices are absurd to say the least. Both Nvidia and AMD are screwing gamers with high prices. Leaving no choice for "budget" gamers but to buy a used GPU. But in used GPU side, as in my recent experience, partner card companies are using excuses to get out of warranty claims. Buying used goods is an absolutely normal practice.
Its just so much easier to be a console gamer. Neither Sony nor Microsoft ask for original purchase invoice (based on my past experiences). The warranty simply starts from the day of console activation.
