CPU or GPU is more important?

[15JG52_Brauer]

Repeated my test (London sightseeing spit) with CPU clocked down to 2.66 ghz - lost 5 fps compared to 4.6 ghz test - will have to try similar tests ith track of London bombing mission to see ho CU affects things whenthere re muliple planes -bt with just 1 plane CPU is not critical (difference between 38fps and 43fps is not noticeable) - also no stutters (but then I have not sufered from that at all so far - probably as my GPU has 1.5 gb vram).
