One thing seems to be clear, if we want to crack keys we use gpu power and we better do it on a desktop computer that can survive the generated heat... That's one of the things i have understood. Anyway we can try to crack keys from a laptop too but with less power, more time needed and hoping for less heat generated...
On my VAIO laptop i could run several virtual machines and try some attacks. But hoy i really want to use my new laptop? I want linux for sure, and kali. I can try to attack virtual machines from another laptop. I mean, maybe i can ask for less ram and power...
Anyway, another must is two usb 3.0 ports. That is a must just to copy data from and to external hard drives. And is a must no matter i will use windows or linux and that laptop, anyway i always haf the feeling to see copying data on Linux much faster than doing it under Windows...
I'm still looking for a laptop that i would like. Seems that finding a laptop better than my 7 years old Vaio VPCS11C5E with intel i5 core and Nvidia Geforce Cuda inside (no idea real models of both) will not be possible unless i want to expend more than 700 bucks... Even if 7 years had passed. I don't even know how much it costed 7 years ago since i was a lucky guy that won it thanks to Frigo Magnum Icecreams :-)
