A reference 980 Ti? You could, but the problem is those cards have a pretty poor fan/cooler on them, so you would end up with a very noisey and hot card, which would be too much for most people.
Nvidia cards have excellent reference cooling, it's AMD that usually has poor designs. But even so, the ACX coolers that companies like EVGA use are quieter and cooler when overclocked than the blower design is at stock and they are the same price. You can easily overclock these cards without them being noisy or hot.
