Graphics card prices are currently in freefall, as the impending launch of Nvidia's 11-series draws closer. Except for a few flash sales, prices for mid-range cards like the GTX 1060 have largely been unaffected. If you've been waiting to buy a card in the ~$250 price range, this is the deal for you.

The Sapphire Radeon NITRO+ RX 580 8GB is currently $249.99 on Newegg, while other models are trending around $260-280. Performance is roughly equivalent to a GTX 1060 6GB, but you get 2GB more memory. This card has RGB LED lighting, a boost clock of 1411 MHz, and Sapphire's 'Quick connect' fan system.
