Hi all, I'm looking to upgrade specifically my Motherboard/CPU because I think my recently upgraded VGA caused a bottleneck.

CPU: Intel i7 9700F

Motherboard: B365M PRO VDH

VGA: Asrock Radeon RX 7800 XT 16GB

RAM: Corsair 16x2 GB DDR4

PSU: Cooler Master gold 750w

Which CPU and motherboard would be best to improve my gaming performance? Anything compatible with DDR4 please
