In November, BabelTechReviews purchased a Gigabyte GTX 1070 Ti Gaming OC 8G video card from Amazon for $489 for the purpose of testing GTX 1070 Ti SLI. Since then, we have reviewed the Red Devil RX Vega 56 versus the GTX 1070 Ti Founders Edition, and found it a worthy competitor even though the Adrenalin 17.14.4 drivers are somewhat unstable. It is natural to compare aftermarket versions against each other, and now that AMD has released stable 18.1.1 drivers, we are going to review the Gigabyte GTX 1070 Ti Gaming OC 8G versus the PowerColor Red Devil RX Vega 56 using 36 modern PC games.
