dmesg

I get "Invalid PCI ROM header signature: expecting 0xaa55, got 0x9125" upon
booting my PC with my new Sapphire RX 470 OC graphics card.
Also there seem to be numerous errors in the dmesg.
I do not experience any major issues, but I also haven't tested any heavy 3d
application so far...

This is harmless.  The driver is ultimately able to find the vbios image.  If
it was not able to, the driver would fail to load.  There is no bug here.

So this error warning will never disappear?

Correct.  The message is not actually from the driver.  It's printed by the
core pci rom code.

Ok thanks for the insight.
Just out of cutiosity, why does the core pci rom code print this?
