Performance help (vr)

i have:

32gb 3200 hz ram

ryzen 9 5900x

3060 12gb

i can play vr but the best i could get it to run is around 40 fps even with all the toolkit and openxr stuff

if i upgraded my gpu to a 16 gig 4070 / 4070ti would this make a significant difference, also will my cpu be able to cope as it is relatively old now
