^^^ this is my suggestion also..
unless theere are upgraded specs.. you're willing to pay 3.5k for an underrated laptop that seems to generate its price based on that badge they have there.. so the laptop is 2k and the badge is 1.5k...
ithe sony one that gwin posted is alot better specs.. but i would still look at building 2 PCs.. one at work with high end processor 6GB RAM.. and high end gfx card to handle your CAD..
home PC sounds like you just want an off the shelf PC to simply browse internet, torrent, etc.. doesnt need to be anything high end..
