I am currently using this, enabled reBAR and I am very grateful for this feature in combination with my 3080 FE and VR. I (subjectively) noticed a an improvement with reBAR enabled. My advice, go for it! Attention: I had to completely redefine my BIOS OC setting. So, you might want to do phone screenshots as for easy reconfiguration, if neccessary.
