Having only 8GB of VRAM seems to be the biggest crippling factor for this A580. I was looking at A770s on eBay and on good day you can get them for quite a good price.
Yeah, for gaming anyway. AAA games are console-first these days, and are finally targetting current-gen (ps5/series x) which have 16GB (though gpu/cpu shared), so 8gb will become a problem.
Only the 8GB model. Hardware Unboxed latest gpu market update shows the 16GB model is selling for $50 above MSRP at $400 and the 8GB model for $280. You definitely shouldn't buy it at $400 since the 6700xt handily beats it and costs $330.
The RX 7600 costs $270, has 8GB of VRAM and AV1 encoding, and outperforms the 8GB a770. So I really don't see an objective reason to buy the a770 aside from supporting a 3rd player in the gpu market (which is a good reason IMO).
