Having additional GPUs may have proven useful for this work since we leapt from barely playable on the GTX 770 to max settings on the GTX 980. The GTX 1080 naturally surpassed the GTX 980 and the RX Vega 64 beat them all, both at stock and with the undervolt and power limit. Based on this sampling of performance data, if you could pick any GPU to play Wolfenstein II: The New Colossus on, the RX Vega 64 would be the best of those test. However, you can very comfortably go with something older and cheaper, like the GTX 980 without compromising a setting. To my mind, that is pretty impressive for a modern game with modern graphics.
