@ smokejumper that system should be able to run ARMA 3 at Ultra settings but Zen 3 is going to be announced on October 8th. if you can wait 2 weeks, you might have better options depending in how much of an improvement it might be. The 12 cores of that 3900x won't affect ARMA. It would be IPC, CPU speed per core, and lowest RAM latency + highest possible speed combined that would make the biggest impacts. I am looking at Zen 3 like many ARMA players here as a potential upgrade too. Read Oldman and Groove C's older post in this thread as they have great advice. @ Fluffyplays Check to make sure CPU and GPU fans are not clogged with dust. I just cleaned my system (AIO watercooler) and vacuum a ton of dust out of the radiator. Gain my performance back immediately.
