What about you look at your local classified fields like craigslist? There's a bunch of use GPU's you can find. As long as the GPU is fairly recent and the seller is willing to provide some sort of proof of payment for the GPU then you should be fine even if the GPU ends up dying on you and you can RMA it back to the manufacturer.
Gtx 970 is a great option
Get a GTX 970 for a little bit more expensive or buy it second hand, amazing value.
