Not exactly a true comparison but I have a Ti 867 with 1 gb RAM 10.4.7. About six months ago I replaced the original 40 gb drive 2400 rpm with a 60 gb 7200 drive. I opted for the 7200 speed expecting snappier performance. It may have provided faster performance [presumably it is] altho I have now forgotten the earlier performance speed. how quickly one becomes used to these things. But a significant downside is that the drive runs hotter and the fans activate much more frequently than with the 4200. On your other topic, I believe that Leopard will work on my machine altho whether I install it is still unknown. I expect that Leopard may not run with its full potential but I am only a home hobby user so all the advanced features are of little interest to me [at the present state of publicly announced features].
