Looks like you were right to be skeptical of Navi. I hoped going to 7nm would give them a huge edge vs Nvidia, but they're pretty similar on performance to power consumption with Nvidia's 12nm cards. Even worse, they're pretty similar on price. 5700 XT is probably the best card for the money out there right now, but it's a Polaris replacement at almost twice the cost three years later (eg $400 for 5700 XT vs RX 480 8GB at $230). Reason I call it a Polaris replacement is because the die sizes are pretty similar. What a horse generation to be buying a gpu.
