With GPU encoding it's important to take into account that GPU encodes are usually delivering way lower quality levels per bit, especially if you're looking for fast speeds. The difference is dramatic if you compare a Twitch stream (for example) encoded with NVENC to one encoded with x264. Of course, hardware encoders let you achieve things that you simply can't do with CPU encoding, so sometimes that quality hit is irrelevant... but if you're talking about whether to use h265 instead of h264, it's possible the bitrate and quality improvements aren't that dramatic when you're using nvenc.
