Hi all, not sure if this is the right place to ask, if not, admin please put in right forum, thx! I'm looking to sell my sons HP Dv6-7312nr. He wants me to build him a gaming cpu, but not sure how much to sell it for? Here is the site with the specs:

Any suggestions will be helpful! Thanks

I think it's worth about $300-$400. Make sure to do a full reset on it so that it sold like new.
