Can I crossfire a hd 7850 1gb with a HD 7850 2gb? It wasn't until after I bought it that I thought about using crossfire and that 1 gb might not be enough. I'm still new at this, so help me out; thanks
 


Why connect it to the 2 gb if they are crossfired? Does it make a difference?
 


It doesn't work like that, the data is mirrored on both cards so as only 1GB of data can be mirrored the OP will have 2 1GB cards in Crossfire and it won't matter which card is the primary but most would have the faster card as the primary regardless of whether it is the 2GB or 1GB card.
