Binned GPU versus non-binned GPU. Better sustained boost and better overclocking.
If you don't care about the potentially better performance and any 2080 TI is good enough, then go with the Black model. Still a better quality card than the Ventus, and much better customer service from EVGA than from MSI, if you need it at some point. Also, EVGA offers the option to buy an extended warranty of an additional 5 years for only 30 dollars or a 10 year extended warranty for 60 bucks. WELL worth the additional money. This has to be done directly through EVGA after you purchase the card, within 90 days of purchase though.

If you want to overclock the card, I'd recommend going with the binned model. Not only will you get better performance, but the binned GPU is likely to last longer under more demanding conditions, than the lower binned GPU is. If you go with ANY of the basic aftermarket card models, I would leave them alone at their default configuration if you want them to last. That goes for ANY brand, not specifically EVGA.
