The PS3 has plenty of RAM, the problem lies with the OS which uses a whopping 91 MBs of RAM. This is not the only limiting factor for the PS3 though, the complexity of programming for the Cell and an outrageously slow disc read speed don't help. The Blu-Ray drive only reads at 9MB/s which is simply inadequate, it is possibly the PS3's biggest limitation. In my opinion, the PS3's architecture is a disaster, considering the R&D expenditures and $900 cost per unit at launch the PS3 should have been much more well designed.
