With Black Friday and Cyber Monday on the horizon, and Nvidia having released a new GeForce GTX 1070 Ti graphics card, it's a perfect storm for discounts on the GeForce GTX 1080. It has already begun—over at Newegg, you can score a Zotac GeForce GTX 1080 Amp Edition for $510.

The card is marked down to $540, but if you use promo code EMCSBBRC3, it shaves $30 off the price. That is the lowest price around for this particular card, and also $40 cheaper than Nvidia's Founder Edition.
