The 590x was great and lasted me around 5-6 years until I picked up a replacement, but it was really just a rebadged 580.
The 580 is a solid card that was an excellent price/performance value and held a respectable spot in the market for a very long time. Many video games now use is as the entry level bar for playability.
It doesn't hold the same "type" of spot, but it's a workhorse in the same way something like a NVIDIA 1070 was.
