Basically you look at gaming laptops and read the specs of the nvidia
card it has ;)

While laptop is not a perfect choice for cracking passwords, if you need
new laptop I totally understand why you want a tool that can be used
*when really needed* to crack passwords. I'm on the same boat, and just
two weeks ago got myself lenovo y580. Pretty cheap beast with i7-3610QM
and nvidia gtx 660m. If you're interrested, little test:

John the Ripper password cracker, ver: 1.7.9-jumbo-7 [linux-x86-64-cuda]

I think it's totally acceptable for everyday cracking ... or it will
tell you laptop isn't good after all ;)

This laptop is what I really recommend, great quality, decent price and
beast of a power. If you need a benchmark of any other particular hash
let me know.
