I've reached out to Amazon and Newegg to determine their official stance and will update this article when I hear back. (It's the weekend, so it may be a while.) In Europe, both Overclockers UK and Caseking will let upset buyers return their GTX 970s.
AMD's pushing hard to convince GTX 970 buyers to join Team Red with that refund money, slashing prices and conducting an #IWant4GB campaign on social media. I'd recommend thinking hard about whether or not the under-the-hood stuff truly affects the performance of the card in your use case before you return your GTX 970, but if you do, PCWorld's massive graphics card roundup can help you find a killer replacement. (Hint: It's the Radeon R9 290X.)
