Something like that maybe, yes, for "very high quality". This machine is a macbook pro with 2.4 GHz dual processor and 4 GB RAM. How much faster a client than that do I need? I checked the lowest quality now and the frame rate there was also about 2 fps. I need "high quality" for my work and I don't think I'll get a much faster laptop than this one.
