Intel Arc A770 vs B580

So, I was able to pickup the A770 on sale for Black Friday at $400 AUD (down from $539). What drew me to the card was the 16GB of VRAM as I plan to use it for photo and video editing as well as some light gaming. I am upgrading from a GTX 970, so I am going to be getting a great improvement overall and will actually be able to play some Triple A games.

My question is, do you think there is anything about the Battlemage series that would mean I should consider switching over to the B580 and cancelling my order as I will likely to get a B580 for a similar price as the A770?

I know nothing is really valuable till proper benchmarks come out, but interested to hear opinions.
