Fiber is Coming to my neighborhood

I just talked to a At&t Technician in our neighborhood and he said they are bringing fiber very soon.  I hope this improves my internet I have cox cable out several times a year working on my internet from cox.  The internet seems to very on my computer when surfing the internet but streaming TV doesn't seem to be affected much.  I am building a system so I don't have my DAC or streamer.  I do have my amp and getting a preamp as we speak.  Would Fiber have any effect on the type of streamer or DAC I look at?  I do assume that fiber will be better than cable.  What should I look for to improve signal as far as jitter?
