So my area just got fiber optic internet, and my provider is offering it for free, so I got it. The thing is, I only have a few devices that are using my network, mainly my phone, 3ds xbob and gaming pc, and it has never gotten close to using all of my bandwidth. So I was wondering, if I got a network card with 2 or even 4 jack connections, would I see an increase in my pc's network connection and the amount of bandwidth it is utilizing, or would it just be a pointless waste of money.
