There are some pros to having this that your average geeks won't have any knowledge of and that's called LAGs using true LACP. For example if you had a NAS box setup with a 2+ LACP configuration you would benefit from multiple connections from the other side. I have an alienware and this works well especially when acronis kicks in nightly for full backups to the NAS.
But for your average usage like gaming and surfing it's pointless. People that call it gimmicky just have limited experience with various technologies and abilities. Good call for asking, no question is stupid, but answers can be.
