That GPU plays all my h264 2160p files, and runs Aeon Nox at 4k perfectly at 60fps so I can recommend it also for older system you want to make into Kodi machines. Here is a good starting point for the quest of building a HTPC:
My understanding is you only HDMI version 2.0 and up is capable of 4k playback at 60fps. I did a quick search of GT 630 V2 on google, which either says it has HDMI 1.4, or doesn't mention the version (implying that it's 1.4?).
Are you sure your GPU plays 4k at 60fps?
nVidia Kepler and Maxwell GPUs with HDMI 1.4 outputs with the latest drivers support 4:2:0 2160/50p and 2160/60p HDMI 2.0 output. This is because 4:2:0 HDMI 2.0 modes at 2160/60p are within the HDMI 1.4 bandwidth - so nVidia were able to retrospectively add 2160/60p support to HDMI 1.4 cards using this slight 'cheat'.
I've managed to get an nVidia 7xx card running 2160/50p and 60p in 4:2:0 running on my Sony UHD - though haven't got it properly running in Kodi yet.
