You'd be wasting your money. Here's how it works:
The signal from the source (let's talk 1080 resolution, for instance, and we won't go into 3D here) is either 1080i or 1080p. If it's "i", it's interlaced, meaning each field (at 60Hz) is half the picture, every other line. It takes two half-frames to make a full frame, of course, so you're effectively getting 30fps. On the other hand, if it's "p", the source is sending a full 1080 frame each time, at 60 Hz, so you're getting 60fps. Either way, the half or full frames are only transmitted at 60 Hz. The source data is NOT 120 Hz, 240 Hz, or 480 Hz.
Your TV, on the other hand, may refresh at these faster rates. In this case, your TV is taking 60Hz source data and interpolating extra frames (if you have something like Motion processing turned on), or just displaying each frame multiple times (or keeps each frame displayed for multiple refreshes). This is after it gets the data from the cable, so the "speed" of the cable has no effect. It's not the speed it's receiving the data, but what it does with it after it gets it. Rating cables for higher refresh rates is pure marketing gimmickry. (rating them "standard" or "high speed" is not)
