I took the info from this video demonstrating the costumes on the GC. Though wiki says that it didn't have them...strange.
"However, it does feature an increased frame rate of 60 for FMV movies and enhanced 3D character model graphics."
I don't know what to make of it.
All versions have those costumes, the Dreamcast and PC have even more costumes. The better character models (really just better resolution, no changes to them at all) are also in DC and PC, however backgrounds are better on PC and DC.
I'm pretty sure that nothing (graphically) on the DC is going to look better than on the GC. Where did you get this information?
Well the GC ports are ported from PS1, the DC from PC. But these are games from a previous gen on new gen machines, comparing graphics is silly at best. They pretty much the same, though some people believe the DC is better, the backgrounds for RE3 certainly are, the only real argument is character and enemy models.

Also, the textures are definitely better on the GC. There character are also less blocky.
