I use Mighty's ROM and was wondering this myself a few weeks ago. So I disabled TF3D and did without it for a few days. I saw no real difference in my battery. I switched between TF3D, HTC Home, and SPB Mobile Shell 2 and they all gave about the same battery life. However, forcing 1X over EVDO while I'm at work (I don't use internet while at work) saved battery.
