Hi,
if you have BPPC card and a compatible graphic card, and that you use mainly CGX & WB system friendly apps, then take the try with MOS, You'll get a huge big boost over a 060/100Mhz, and you'll still be able to listen radio.
But don't expect any gain of speed for the PPC if you use the original Warp "build", use their MOS release instead :rtfm: .
