So I've been thinking about buying a powerful laptop, and I was wondering if anyone had personal experience with them. I'm in the military and I'll be in need of something more portable than my gaming desktop that I currently have. I don't trust people around my belongings, and just because you may serve the country, they still are thieves and other things.. haha. Also I was wondering if it was worth it to get a SLI laptop? (Dual graphics card)

Give me some thoughts and feedback!!
