This didn't work out for 970 owners in the end. The 970 replacement is $450.00 and that measly $30 (which will take forever to even receive) won't be enough to help many people replace their funky ass 3.5gb 970 when it starts stuttering, if it hasn't already. Nvidia screwed millions of people with the 970 and then raised the prices on the replacement product (GTX 1070) by over $100 from what the 970 was. If Nvidia gave a damn about making this right, they would allow people with 970s to buy a 1070 for the price they paid for the 970, plus the $30 refund.
So, they give you a proper replacement product for the price you paid originally, then the $30 on top of that. People with 970s might not be happy about being stuck with a 970, and the only replacement product magically increased in price by over $100. And no, the $380 launch price of the 1070 is a load of crap. The cost is $450. The only other option if you want the same price bracket is to go to a low end 1060 or to switch to AMD.
Nvidia hasn't made this right. They need to do more to show they really respect and care for us gamers and that they are sorry for this situation. A discounted 1070 for 970 owners would go a long way to make up for it.
