Resizable BAR can give you a significant boost in gaming performance

I've known about Resizable BAR for years, but never bothered with it until now. One of the things stopping me was the fact that my main SSD was formatted in the MBR standard instead of GPT. To use ReBAR, I needed a GPT-formatted drive; otherwise, I couldn't use UEFI, and therefore, Resizable BAR. I recently updated my motherboard BIOS and finally decided to check if Resizable BAR would be worth it.
