Hi i just want to ask, whats the proper way of installing drivers on an ATI card... Does it involve Lucid virtu mvp or do i just uninstall and install the donloaded drivers after that... I am just asking to be sure if there is a better way of doing.... And a quick one, i have an asus z77-vdeluxe and which is better, installing lucid virtu mvp from its homepage downloads... Or from ASUS drivers, looks like they have exclusive drivers for the thing
