Bought an ASUS ROG Strix Vega 64 off someone online for $525.
I set it to Power Saver mode because I read that it outputs less heat and noise with minimal performance hit. I was surprised when I ran Fire Strike because it still had a score of 23,000, a bit higher than I expected and right in the GTX 1080 territory.

Did a bit more benching with Unigine Valley. Looped it for 45 minutes and the clocks stayed steady at 1500/945 with the max temperature being 70 degrees. Fans were pretty quiet the whole time.
I normally opt for NVIDIA cards if possible due to the better power efficiency and heat output compared to AMD, but I'm very pleased with this one.
