Lot of varying opinions to say the least.
Been following Vega for a while, and hopefully will pick one up, if the performance is there. I have a freesync 1440p monitor.
Vulcan was the catch for me there, from what little I do know Vulcan prefers AMD. However it wouldn't have been exciting if this was Vega vs 1080. But against a 1080ti? Impressive. Even though this is subjective.
