To answerr the question honestly. I've had 68882 FPU in a few of my 030 cards and I've never felt that I gained anything significant from it. Now with the FPU built into 040/060 that's a hole other story. Only about 1% of Amiga games will benefit from an FPU and then only slightly when it's a slow 68882 FPU.
That said, for 5$ incl s/h I'd buy it anyway just to be prepared.
