In addition to the GTX 970 sold and shipped by Amazon, BEFORE 19 MAY 2015, there was the offer with The Witcher 3 offered, but if you do not receive the code after 2-3 days please contact the Service amazon consumer, that's how I got it (they had trouble with). FYI the offer is here ;ie=UTF8&node=6170224031&pf_rd_m=A1X6FK5RDHNB96&pf_rd_s=merchandised-search-3&pf_rd_r=10194XTT5KYHD58Z2XNA&pf_rd_t=101&pf_rd_p=611299307&pf_rd_i=427941031
You only have to follow the instruction to get the game (note that the game will not be on Steam with this code).
In short, if you have the means please take this graphics card;)
