Looks like this one will allow the use of 2 different NVIDIA based cards like the 9800 series and the 200 series as the chip is stated as being the replasement for the nf200. The move to this chip may possibly be because NVIDIAs move away from motherboard chipset development so production of the nf200 may be headed to discontinued status. The Lucid will work in the same manner allowing the SLI of like gpus as well as that of gpus of difference constuction. This also continues to allow Intel to have SLI support with their chipsets while not having to rely on NVIDIA for supporting chip to allow 3way + SLI.

The use of ATI and NVIDIA video together I think is still some time away because as stated in earlier post, driver developement is always lagging for software/os support. The use of this chip along with ati and nvidia gpus would result in having to use 3 seperate drivers to allow for channeling through chip for each occupied pcie channel. In time I see Lucid possible developing drivers that will support both that will also have the driver for the Lucid chip implemented into the drivers. This way they could handle all 3 platforms with 1 set of drivers. This development tho is still quite some time away I'm sure. So the use of the chip for an individual gpu platform (ie nvidia with nvidia or ati with ati) would be more the case of use at this point in time.
