I'm surprised by the OpenGL Test. I get 185 on my 2.33 GHz MBP with its Mobility X1600. I would have expected a lot more from the iMac's superior HD 2600 Pro. OTOH it might just be a driver issue that Apple needs to fix with an OpenGL update. And of course XBench doesn't exactly have the reputation of being reliable either.
