Let the hive mind of Engadget get that for you.
"What's the best gaming laptop for under 1,500 bucks? I had my eye on the P7805u (Gateway), but it seems Best Buy has run out for the time being. Also, as a secondary question, I like the specs on brands such as iBUYPOWER and CyberPower and the like, but are they reliable? I'm a little worried about buying labels that aren't huge like Dell, Gateway, etc. Thanks!"
