A bigger pipe will certainly get used occasionally, but I can't help but think that the vast majority of that pipe will sit completely unused for a large percentage of the time you're paying for it. Torrenting is just about the only circumstance I can think of where you might actually get to fully utilize that pipe, specifically because you aren't bound to a single upstream, but you'd almost have to go looking for files large enough for that throughput to matter. An uncompressed blu-ray is what, 25GB, and that's still less than an hour to download on a 60mbit connection. Given that compression is a thing, it just seems like your chances to actually utilize it will be minimal at best.
