I have some questions about running crossfire with two 7850's. I already have a Sapphire Raden hd 7850 2gb OC edition and therefore i was wondering if i have to buy another OC edition for this to work. I am not very good at the more technichal aspects of pc's and i cant seem to find an answer and therefor i am asking you.
I am also planning on upgrading from 8 to 16GB Ram because i read on AMD's website that it was recommended.
