Hello, I have a couple year old laptop, just a Presario, not a great gamer but works for me. But sometimes I would like to do a bit of gaming but not with this video card and I know I can't change it. As 99% of the time I use it at home what I would like to do is connect it to a desktop for it's power and ease of upgrading but use the laptop for screen, keyboard and speakers. It would be great if I could still use my laptop alone for easy things but switch to desktop for games. Possible?
