I do not want to game; I need the laptop for petroleum industry software. 16 gigabytes RAM is the minimum requirement for my Petrel (Schlumberger) software, but the computers run slow on that. Over 16 megabytes will better. A friend of mine got one in California with 32 gigs of RAM, and even that runs slow with monster-size 3D seismic surveys. I'm in Houston. Where can I buy this?
