If you already have the R5-1400, get a 1650 Super....(if pondering a CPU purchase/ upgrade, and your mainboard is compatible, the R5-3300X is giving the best $120 experience imaginable)
The 1600AF is another nice option, where the 6 cores/12 threads stop the low dips in frame rates in many games where 4 core systems often have issues...(excluding the 3300X, which is doing stunningly well for 4c/8t , giving new life for 4c/8t CPUs previously thought inadequate, but, seemingly and surprisingly giving 95% of the performance of the R5-3600)
