It just gives you an FPU, now contrary to popular belief, and experience from doing this when the machines were apple's current systems... there is next to NO real speedup for general purpose apps.
check out wikipedia or similar for an explanation of FPU's, but in reality, there are a few apps that use them.. the main things I used them for was 3d rendering (why bother on a 68k these days), font design (works without, but is slower to image to postscript), and a few photoshop filters that took advantage of them...
in addition, if you run up against software that NEEDS an FPU, softfpu works as a slower alternative to at least let you run it emulated.
FPU's are amazingly powerful on 68k, but their limited usage meant that their inclusion into LC and Performa class machines was pointless as 90% of the target audience would never need one.
