Sup half/g/ods,

I have to admit even though I work as a System Architect in an international concern I haven't kept up with todays tech.

Now that I'm moving to a new place I thought it might be time to get a new Laptop. So please tell me, for a decent office/home use-machine, what specs should I go for?
Also, what would it take/cost if I wanted to push a lil bit of gaming on there?

Any help would be appreciated.

Pic might be unrelated. Will take first pic i find on this phone.
