[quote name='Sleepkyng']what are the real advantages of G over B?
if your house has cable, or dsl, isn't that going to bottleneck it anyways?[/QUOTE]
Distance from unit, speed, future use.
G is as low as Id go now. I think theres even Super G. (too $$$ for my tastes) Anyway, if you shop deals you can get G (on sale) for B (regular price) Why not take the best for same money I say.
Youd have to switch over your whole system to have it all run a G speeds but sooner or later you ll switch anyway. I say take it part by part.
