Hello you amazing people and hope you're having a wonderfull day !
While browsing through my BIOS just to make sure everythig is in order I stumbeled across the setting category mentioned in the title.

PCIe Slot Configuration ----- Auto
DMI Gen2 Speed ----- Enabled
3DMark01 Boost ----- Disabled

Now I am wondering if I should change those to get the best and maximum performance out of my new Sapphire RX 580 8GB Nitro + GPU or should I leave them as is ? Also if someone would care to explain what the setting does and what's the difference between it's available options ( Gen1, Gen2, Gen3 ). The card is mounted on the 1st and proper PCI Express x16 slot, running at x16 (PCIEX16) on my GA-Z97X-UD5H-BK motherboard.

It's been mentioned prior, that 3DMark01 Boost is only a bypass to fool benchmarks. You should look at keeping things as cool as possible while you're on those overclocks. What is the make and model of your PSU? If your system's running fine as is, don't bother with it. You're already at your boards limit. BTW, which motherboard PCB revision are you on? There are three listed on Gigabyte's site, with rev 1.0, 1.1 and 1.2.
 
If everything is working fine, then you should not change these settings.
Gen1, Gen2, Gen3 refers to PCIE 1.0, 2.0 and 3.0 signalling standards.

You could change setting to PCIE 3.0, but sometimes this can introduce problems (unstable gpu operation, crashes, BSODs). Try and see, if you're curious.
May need to revert back.
