i have seen ur new motherborad Intel® Desktop Board DX58SO and his sepcifications in the video colum
Nvidia SLI* and ATI CrossFire* multi-GPU platform support enables two graphics cards to work together for ultimate 3D gaming performance and visual quality
Full support of next-generation ATI CrossFire* and Nvidia SLI*
my dear frd its is possible a gamer need that motherborad becase the gamer never use integrated 3D card becase the preformce of that 3d is low as compare to the ATI or Nvidia open cards in markets now if u free space for 3d card is more better just like in D975xbx2 it is plain motherboard and you also give and SLI or cross fire So how is you give that opton to user integtrated 3D card of ATI & Nvidia so man think again about that motherboard in the case of gaming.and you also only Support for a Intel® Core™ i7 processor y ? where your user of CORE AND EXTREM processor gone.if they wana update there CPU . they tottaly buy new PC . its too much expensive.
