Though the market is particularly bad here, because an RTX 3060 12 GB (not Ti) costs between 310 - 370 EUR and an RX 7600 XT is between 370 - 420 EUR.
Either way, I'm happy that these cards exist because Battlemage is noticeably better than Alchemist in my experience (previously had an A580, now it's my current backup instead of the old RX 570 or RX 580) and it's good to have entry/mid level cards.
