While 85,000 polys is a lot, that's not responsible for any slowdown alone. I've had scenes with over 100,000 poly's going with animated characters, shadows, physics, AI and a lot of other stuff without dropping any frames on a videocard a lot slower than a 9800 XT.
So while I'm not advocating leaving the scene as high poly as it is ( though it's hard to judge without seeing it ) there must be other issues here too.
