Hello, before i get too far as far into my question i would like to clarify that i do indeed know this is an older system. and i do know i should update to a modern laptop but this one has served me well. i have a HP Pavilion DV4 2165dx that is running windows 10 (idk if that info helps) but it has a removable internal optical drive that i really dont use much and would benefit much more from added graphics hardware. does anyone know if it is possible to successfully install a graphics card into an optical disk drive? and if so does anyone know some cards that would be best compatible with my system? thanks
