So I recently upgraded my rig to a Ryzen 3600, 16gb 3200mhz Corsair Pro Vengeance, however I'm still running my EVGA 970 ACX, which is showing its age. I currently run a 4k 60hz monitor (mostly played on my Xbox One X until now), but I'm thinking about switching to 144hz and also getting a new card? I know most people say wait for the newer cards but what would be a decent card in the price range of £250-£350.
