I just found something interesting that may make me go for an ATI card instead of Nvidia.

Although it costs about $450, it has a power of two HD 3870 GPUs in a single card that only takes up a single PCIe port. It can also be expanded to crossfire which will turn it into basically Quad GPU system. I know this was done before by Nvidia with 7950gx2, but I believe that this is the first DX10 card to do this.
Another thing I found out is that the sandard HD 3870 is supposed to receive a drive update which will allow it to work in Quad Crossfire as well. The down side is that it will take up 4 PCIe slots. What I am wondering is which of the two possibilities will yield better performance.
Finally, this appears to me as a good reason to not get an Nvidia card, especially for the people that want to get the 8800gtx which is around the same price. I am not sure about benchmark comparisons between the HD3870x2 and 8800gtx, but I do know that the ATI card supports DirectX 10.1, which the Nvidia card does not.
So, what do you all think about this?
