E: what I gather is that multiple BIOS allow for multiple settings for OC purposes. Other than that, is there any benefit to getting the classified over the 980SC?
Higher overclock from the factory as you can see. The PCB is also custom, and usually about an inch wider to accommodate extra components to aid in overclocking. Notice, these cards are generally aimed at extreme overclockers and always perform better when in the low negative temperatures, as that is what they are built to love. You can get good performance on air and using watercooling, but when running phase change, Dry Ice/Acetone and Liquid Nitrogen, these cards shine compared to reference PCBs. On that note, if you are not using extreme cooling, you can sometimes get the exact same performance out of the reference PCBs.
These are MEANT for extreme overclocking in general. The normal people, like me, usually get them and leave them at stock settings for gaming. When I can finally afford DICE/LN2 pots or a phase change, I will move to extreme cooling measures.
Too many people purchase them and then say "it doesn't say meant for extreme blah blah blah..." it is. They also generally have 5 of the brightest LEDs you will ever see, that can NOT be turned off or controlled. These are meant for the time when using the extreme cooling and the vapors block out the ability to see if the Core, VRMs, and such are OK. If they are not, the led will shut off, killing the light to the corresponding faulted section of the card giving an alert that something failed to function.
