I have four gaming systems on my network at home and I have tried steam on all of them. With three different operating systems and four different hardware configuration (including a dual processor system with a gig of ram), lets just say we quickly removed it from all the systems. Counter Strike Performance suffered enough that the users of the systems complained (to say the least). If I wanted that kind of performance after all the money and time I have put into my systems, I could just hookup my old P233 with 128megs of Ram with my old voodoo3 then plug the phone line back into my 33.6K modem and dialup AOL... Well that was the first and last impression I have had about STEAM. I guess if steam is going to be needed to play VALVE games online then I guess I will be playing other games. The upside to all of this for me is that it makes it easier to decied where my gaming dollar will not be spent.
