I am almost ready to get rid of this setup. An FYI, Duals run so much faster than a single at the same speed it isn't even funny. I am now a believer in the Duals. This runs Tiger perfectly, and I can even get this setup to run Halo at 1600x1200. Halo is my test bed for many systems since people like to complain it doesn't run right, since it is so bloated and poorly programmed on the mac. Please do not discuss price on this forum. if you think you might be interested e-mail me.
