In general, they'll be playable. But a lot depends on the game and updates for those. Apex in particular isn't exactly well optimized, so can see large frame swings, fortnite has issues with cheaters and every time they implement an update to fix the problem, it seems to make fps drops very erratic. Lots of ppl complaining of going from 150fps to under 50fps overnite. As said, BF5 can be hard on any quad, that's one of the games better suited to 8 thread cpus, so intense or heavy server battles will be brutal. It's going to be like that from now for quads, multi-player AI just sucks the life out of them.
