See https://developer.nvidia.com/nvidia-vide...NCFeatures and https://developer.nvidia.com/video-encod...ix#Encoder in regard to which GPU supports what encoding features.
Sadly those sites do not show the max macroblock count, but my guess is to encode to HEVC 4k at 60fps you probably need one of the cards which support 8k H.265 lossless encoding.

Ps.: I would recommend to write an email to NVIDIA support and ask then which current card supports HEVC 4k encoding @60fps through NVENC before buying any such card.
