Does anyone know what the max screen resolution would be if I plugged in a monitor to a NEW MBP 13" with the Nvidia Geforce 320m? 1440x900 or 1680X1050 or ??? I assume it would be 1680x1050. I want to use it for running Photoshop CS4/5. Would this work out ok? I know the i7 17" would be cool but the $$$ is just more then I can afford right now.
