Ah, okay. Thanks for the advice regarding the RX cards. I found an RX 580 8gb for a very similar price that I could for a 4gb card, used but seems legit, so hopefully I can acquire that card.
As for why I don't want the 1600AF, its purely because where I live, first gen ryzen is similarly priced to second gen, to the point where I can get a 2600, still with markup because where I live, but much cheaper than the regular 1600. I could only find the 1600AF on one website, but heavily marked up still, so at this point the 2600 seems to be my best choice. I tried finding used first gen ryzen chips, but even then they would just by shy of the price of a 2600. So rather than getting a used first gen, new second gen ryzen seems to be the best option I have without spending too much.
