So far as my own reading goes, it seems that the Intel 975 chipset natively supports ATI's Crossfire, but when running 2 cards it will run each card at 8x, not 16x. While both ATI and nVidia have made announcements regarding Intel/Conroe support in their newer chipsets (the Xpress 3200 or the nForce 5xx series, respectively), neither appears to have any of their chipsets on any commercially shipping Intel-based Conroe-supporting motherboards at present. I have seen "review" articles on both the newer chipsets and Intel-based motherboards that have them (here and on other sites). I have also seen many boards that are AMD Socket 939- and AM2-based with these newer chipsets. I cannot, however, find any Intel-based boards with these newer chipsets on them on any manufacturer web sites (like Asus or MSI or the lot) nor on any of the more popular retail sites (Newegg, ZipZoomFly, etc.). I await them (somewhat im)patiently.
