Question LEGACY BIOS

[Rifkyy]

Does it affect performance? because I just changed the legacy BIOS motherboard before i using UEFI so it feels very different in gaming performance even though all components are safe, nothing has been replaced or damaged. My VGA is RX550 i5 3470 Samsung B75 motherboard, previously I used Bulldozer H61

Welcome to the forums, newcomer!

When posting a thread of troubleshooting nature, it's customary to include your full system's specs. Please list the specs to your build like so:
CPU:
CPU cooler:
Motherboard:

OS:
Monitor:
include the age of the PSU apart from it's make and model. BIOS version for your motherboard at this moment of time.

Ram:8gb
SSD:rx7
GPU: sapphire rx550 4gb

Case: infinity noir
OS:windows 10 64bit (10.0, build 19045)
Monitor: lenovo l22e-30
Bios version: amibios version P02KQM.096.120709.MK

Does it affect performance?
Samsung B75 motherboard, previously I used Bulldozer H61

No. It doesn't impact performance.
Neither H61 nor B75 nor Q77 boards allow overclocking.

I'm assuming you didn't reinstall the OS after the motherboard swap, if that's the case, then that would be the reason for your 10FPS drop, either that or your platform has bloatware on it hogging some resources.
