if I buy Ryzen 7 1700 ,with motherboard memmory, will my system suffer if I keep my r9 390 8gb.

Im thinking of buying :(ryzen 7 1700,supporting motherboard,and 32gb ddr 4 ram,costing about 550 GBP).

I would swap it with my:fx 8320e 32gb ddr3 memory and motherboard.

would keeping my R9 390 8gb be good for gaming or would it be bottleneck.

I currently run 4k monitor and most games run fine at 4k at 30-50 fps.
