Is that good for fortnite etc
Is a strong card, about the level of a 2060, ie between 1070 and 1070ti, but with very strong variance in the games.
However, it does not consume very little with ~ 210W and is not much better than a 1660ti, which is up to 30 euro cheaper and only draws a damn low 120W.
If you can shoot it cheap and or what can start with the AMD Reward games (DMC 5, Division 2 & Resident Evil 2), get it, otherwise I see Nvidia at FullHD with the 2060 and possibly 1660ti better placed.
