I feel sad posting this, but I lost the link to my graphics card, I have a 5770, and was going to buy crossfire... How do I tell the exact name and model # of it? or does it matter who I buy from (I've heard it both ways... Just thought it was easier to buy from the same people) I feel like an idiot posting this (I should know this!!!)... D,=... and if it is fine buying from anyone, I don't have a "fat" card, does that matter?
