I am getting my dual 1.8 rev b G5 with a 160 gb hd 1 gig of ram, new flat panel 20 inch apple display, logitech mx 510 blue mouse, and white creature speakers. What do you think of my rig? I should be able to play doom 3 right? Oh and i have the ati 9600 128 mb in there nw waiting for ati's answer to the 6800. Probably upgrade video card in 6 months.
