Keep in mind also that transmission line effects are important for video signals and for hi rate transfers. The length of run of the cable comes into play when considering transmission line effects -hence a reason to use a cable with the proper characteristic impedance when the wavelength of the highest signal component approaches the length of the cable. Bandwidth of the cable, is another factor to consider for high high rate transfers of data. Jitter is affected by both.
That being said - and back to the OP's upgrade question - my recomendation for all your cable needs (sounds like a pitch but its just from a satisfied customer) is Blue Jeans Cable - fair pricing , quick delivery, there is no hiding the ball on their products - you can find their cables and connectors at the manufacturers' web sites prior to buying and for the most part they use Belden - a recognized industry std manufacturer, the guys on the other end are practical, their workmanship is professional, they will provide the length you specify, and there is no hype.
