Just got a new RTX 5070 TUF. Seems to be a seriously good overclocker with a quick lil OC. How much does CPU affect the graphics score on Time Spy?

Seems to clock really well, memory as well. Now i'm wondering how much does my current CPU hold it back in this particular test. Does anybody have insights? (platform upgrade is coming btw this is an insane mismatch, it's only temporary)
