depends, if you're running a 50-100ft ethernet line from your modem to your pc, you might not see any higher bandwidth, but your connection stability may dramatically improve. Something not a lot of people really opine on is the quality of the shielding and signal integrity of their cables, since they are fairly niche variables for most people. I live in a fairly populated apartment complex where there are 20-30 wifi signals broadcasted at all times around me, that in combination with my cable being a 100 ft run from modem to pc, I had a lot of signal degradation and crosstalk that really hindered the stability of my connection. If I ran a speed test for instance, the line displaying my connection looked like a kids rollercoaster at 6 flags, up and down all over the place, even though the bandwidth was normal. After upgrading you can see the line displaying the connection is exactly how it should be, ramping up smoothly to a perfectly straight line once max bandwidth is reached.
