with the exception of opengl performance, i wouldn't be surprised if it's faster than many g5 macs, and perhaps all g4 macs. the speedup from moving to intel is huge. although the core duo mini won't be much faster than the core solo, since processing by default will only use one of the processors.

however, i've not tested much.. you might try some things from the exhibition page at an apple store to get the feel for how it works.

Thanks for the info!
