Graphic render engines throw work out to total available Cuda and GPU mem. 1110wattage sufficient in Z800, but available cable outlets apparently require some creativity for a dual install. Purpose is only graphic rendering, so SLI and extra monitor not wanted. Price points on this potential rig now way down. Anyone out there accomplish this with any dual GTX 's on the Z800? Any such success with specific instructions really appreciated. Thxs much...
