I currently own an Asus GTX dual 1070 graphics card. I was looking into buying another one to run SLI;however, when I went to go look to order one, there was three different base and boost speeds and I have no idea which one mine was. I know I have to purchase the same card, but do I have to purchase the same speed one as well? If so how do I find out which one mine is? Also, if it helps at all, I ordered from amazon. Thank you so much everyone.
