chiamon said:I dun think SLI is possible in the Mac Pro as it does not use a SLI compliant chipset. Intel chipsets do not support SLI. Anyone knows wad chipset the mac pro is using? can't find it in the spec sheets.
I am going to guess a 5000V as it only supports up to 16GB of memory as opposed to the 5000P and 5000X which support 32GB.

EDIT: Although Apple did claim 21GB/s off bandwidth, which seems to only be available on the 5000X.
