i do not know of anyone who has successfully gotten that many cards working under windows.

use linux. follow this guide: https://hashcat.net/wiki/doku.php?id=linux_server_howto

I never using any linux. Can i using graphics like on windows, or only text box ?

[epixoip]

that guide will install the openbox window manager and a terminal emulator so that you can use a graphical environment if you wish. however, you will still need to do everything from the terminal.

if you want a full desktop environment, download the full ubuntu distribution, instead of ubuntu server.

[epixoip]
