Although saving $100 is nice, PS3 games use the hard-drive for cache to reduce load times...some games have even shown to use upwards of 5 GBs just for the cache space. Add in what the PS3 OS takes up and that leaves you little room for other uses for the remaining 10-12 GBs. I would get the 60 GB version. I think you would have an easier time finding the $600 one anyway.
