Pros
Cons
Con Thick card
It's more like 2.5 slots thick and cannot fit more than two per PC even with an 8-slot chassis. You'll need full-size cases to fit more than 2 cards. If you want, you can mine ETH or else one bottom card fan will rest on top of PSU.
Con Not much of an upgrade performance-wise
Comparing the cards performance to Sapphire Radeon RX 480 Nitro+ 8gb, we see an ingame improvement of less than than 5 FPS. The average FPS of Rise of Tomb Raider improved by 4 in FHD and 2 in QHD. If you have an RX 480 card in your box, the upgrade is not worth it. Though, if you happen to be running something older, the SAPPHIRE NITRO+ Radeon RX 580 is a great card to upgrade to.
