An FPU will make absolutely no difference in Games.
Go render a 3D pic in a Ray Trace program like Imagine. Then take your FPU out, install the Integrer Version of Imagine & watch it CRAWL through the Render. Even the Beach Ball draw in AIBB will be MILES slower without the FPU.
Ray-tracing & DTP programs along with Database progs will fly for your FPU. ;-)
