whats the minimum requirment for Gcube emulator for mac?

[kenmasters1983]

i am going to be buying another powermac G4 soon and need to know what the requirements are for running the Gcube game emulator for Mac Osx 10.4

i am thinking of buying something with the specs..

1.5ghz G4 with 2meg cache not a dual monster btw.
1.5gb of ram
80gig 7200 rpm hdd
dvd-rw burner
geforce 6200 agp modified

now what kind of framerate can i expect with this setup??

i know the gamecube processor is PPC based so it should offer a speed improvement over windows gamecube emulators right?

i need to know from some who is atleast running a mac with a G5 or G4 with mac osx 10.4..

also please no mac osx86 or hackintosh's

well i guess thats it.
