High end cards are so dull and boring, this end of the market is much better and IMHO more exciting to see just how much performance you can get from a low priced card, with efficiency only playing second fiddle.
I am really looking forward to seeing the data for the 5500XT and the rumoured 5600XT, alongside the pricing. I know AMD have been very aggressive with the RX580 and RX590 recently and having a card that is slightly faster with a lower cost would be ideal, especially since the power draw will likely be quite a bit lower.
If they push them out slower than and RX590 and at s higher price, I've no idea how they'd expect to sell then
