Just like I did with the RTX 2080, saving some from a bad investment, when it comes to price to performance for mining. Below are some of my results when testing the new AMD RX 590 graphics card mining performance, now so far it is just ever so slightly better than the RX 580. I have tested one Bios mod on the RX 590, applying an RX 580 modded bios with no problems, and the website says the Graphics card comes with a Dual Bios switch located by the 8 + 6 pin connectors, which is handy if your Flashed Bios makes the card unstable. There are two Bios modes "Performance" or "Quiet" mode, the card comes stock with Performance enable which is what I was on when I flashed custom Bios to allow Memory clocks of 2300 Mhz. This card is using MICRON memory, just FYI. At stock settings, the card hated anything about 2000 Mhz and kept crashing, but after the mod certain Algos let me use 2300 Mhz.
