I know 512 mb is pityfull, apparantly Vista need 2gb for optimal perfomance blah blah but thats all hes got! I keep trying to get him to put xp on it but he doesn't seem interested. He has seen my cs4 version and fallen in love with it. But i am not too sure that his machine will run any? I have googled it and think it should run photoshop cs v8 by the looks of system requirements, but i am not too sure whether it is compatable with Vista? Any help appreciated.
