it's a fat pci-express card and it takes up 2 slots like the 6800 ultra.
I have a question I currently have a nvidia 6800 ultra but I want to upgrade to the nvidia 8800gtx. NOw I have one question, does it require a sli mother board?; because I do not have one installed in my computer. I read somewhere it takes up two pci card adapters or something similar or do they mean slots like the nvidia 6800 ultra. Thanks!
