Hi, I'm new here, wonderful community! 
I'm mining litecoins and got myself a MSI 7950. However, all the 7950s have pretty much ran out already and I can't find anymore MSI's. I'm thinking of getting a Sapphire Vapor-X 7950 to go along with the MSI. Will this work? Will mixing it have conflicts on cgminer? Is it ok if I also mix MSI with Sapphire and Asus? 
Thanks so much for helping!!
