Windows 7: Installing dedicated video to my laptop

hey guys, my hp laptop doesnt have dedicated video, is it possible for me to install one? or by default, all laptops doesnt have a slot to put in the dedicated video i want?

well depends on the laptop. Some manufacturers use the same reference board for all models, so a redundant slot may be present. but its unlikely.

also power supply may not cope, heat ect ect ect..

if you want to play games, a pc is your best bet. a gaming rig can be built for as little as £400
