I should have checked the stats before pondering how the PS3 would do on F@H. 15,000 PS3s are managing more TeraFLOPS than around 200,000 PCs of various types. Impressive. We shall see if the enthusiasm lasts. There's discussion in various places about how energy efficient the PS3 is compared to some PC platforms and it seems it's not as good as far as gaining F@H points. There are people out there who have large numbers of dedicates machines running this sort of project. I just saw an example of one whose electricity bill is nearly triple mine. I can't afford that and would find it hard to justify unless I knew the electricity was from a renewable source. Maybe when I build my own wind farm I'll set up some PCs to use the excess power. Meanwhile, my puny box will be turned off each night.
