Can I install an integrated video card on my hp pavilion dv6660se?

No, you can't it is physically soldered to your motherboard. So just deal with the Intel GMA you have|||no if you have a desktop you can easily get a whole new motherboard with video card for about 300 but if you have a laptop it would be very pricy and difficult to do that.|||This laptop has no means to upgrade the video. There are no slots for a video card.|||No. integrated means it is physically part of the motherboard.
