ATI CrossFire Xtension v1.0
ATI CrossFire Xtension seems to be a cool utility. It allows you to create custom profiles that will force CrossFire (ATI multi-GPU solution) support on non-supported, or new, games and applications, both for Direct3D and OpenGL.
If you have the opportunity to test it with FurMark, please post a comment.
