Buy the required video cards. It is desirable that the amount of RAM of the video card is 6 GB or more.
Do not buy very old video cards, if not extra funds, then it is better to go into another business.I would recommend you to buy nvidia ideocards, starting with the 10x0 series

If you want to do mining , you need to buy a better GPU. And that's not a easy task now
