I'm thinking of buying an sli compatible motherboard and was looking at this gigabyte model ----> http://www.newegg.com/Product/Product.aspx?Item=N82E16813128358 <------ in the specifications it says that the motherboard supports two pcie x16 2.0 slots, but one of them is running at x8 model. i'm not sure what this means, does it mean if i buy a second 8800 gtx and put in sli, does it mean that the 8800 gtx will only work at 50% of it's potential? Can anyone give me any advice on this? any will be appreciated! thanks! :wave:
