I ended up getting a Sapphire Nitro 64 in the recent deals with the intention of selling my existing silver reference Vega 64 card. With the free games, quieter and faster running card it went ahead. I've been noticing a few strange things. For example running the division at 4K, pretty much all settings at Max I was getting around 40 FPS. I tweaked a voltage amount on the P7 core state by 10 units and the FPS was running mid 50s to 60 on the same game with exact same settings in game and no other changes on wattman. The core clock did remain the same too, give or take perhaps 2/4 mhz here or there at 1578. I found that very odd, so will have to do some more investigating as something doesn't add up when getting such a performance boost. I was also thinking of getting a larger power supply and trying out crossfire too.
