Need advice on a new MBD-CPU-RAM combo

Hey guys, this is my pc specs

OS: Windows 10, 64-bit

CPU: i5-4460@ 3.2GHz

RAM: 8GB x1, DDR3, 1600MHz

MBD: Asus H81M-K

GPU: Asus Phoenix GeForce RTX 2060@ 6GB

STR: SSD, "Patriot Burst", SATA-III 6.0Gb/s | HDD, "Seagate"

PS: Coba CS-552it 82+(edited)

I play black ops 4 blackout and most of the time get around 47-66 fps regardless of graphics settings (making it known its not my gpu's fault). I wanted to ask what MBD-CPU-RAM combination would you guys recommend under $200 budget for my gpu power to be unlocked fully and like get a 3-digit fps?

​

Thanks in advance!
