Will there be support for nvidia SLI option or will only ATI crossfire work ? Cause I know it is technicaly possiblebut will the nvidia driver support it or not ? I really wants to know this because I'm going to buy a new mainbord CPU and GFX but the ati r520 won't be out i time from what i've heard, so I was thinking of the nvidia 7800GTX but I also want to ber able to make a sli setup from it.
