it is the same except it has 32 megs or 64b ddr ram instead of the sdr or the 128b ddr ram that the gts comes with
and it is a little cheaper than some others Herc and asus to name a few)supposed to be like $110, least that is what buy.com has it for
from what I have read there shouldnt be that much of a performance difference between the DDR mx board by creative and other SDR boards, this is due to the 64 bit archetecture of the ddr ram, kind of like celeron syndrome, and rumor has it the ddr either wont be able to overclock as well as the sdr boards or will be much better, but this is only speculation since there are no actual reviews of it yet
