We will be using it for mostly normal stuff like email, internet usage, Word, etc. I do have some simulators I will be using that hadn't worked on my previous laptops very well because the graphics took a lot of juice so it really lagged a lot. So I would like a really good graphics card and processor to prevent that.

Other than that I don't know much about computers. I've played around with the customize options on HP and Dell's website. I'm not sure if there is any one thing I should be looking for. Any suggestions would be great. TIA.
