^ Doubt it, otherwise we could buy $200 7970's if we just refuse the Never Settle bundle. Because its AMD/Nvidia that are taking the cost of game bundles, not retailers unless they are running their own special.
You could just sell off the key to recoup some of the cost of the card. The aforementioned Never Settle bundle is currently going for ~$60, which is a decent enough.
Back to the original topic (even though the thread is necro at this point).
Im surprised Newegg even bothered to respond to the RMA request, you clearly state you were dissatisfied with the products performance, which basically equates to changing your mind about what you want. Many retailers have it clearly stated that they wont refund items purely because you changed your mind on what you want.
Also its a 6670, what kind of performance were you expecting from a last gen entry level card? Not like there are tons of benchmarks online or anything.
