Leftie - 23:50 (18-11-2013) i think it has an onboard controller (don't know if its as good as a dedicated one) and you save pci(e) slots and still run quad sli/crossfire which btw is a bit strange on a z87 chipset as it only supports x4 x4 x4 x4 if i remember correctly and yes only 32GB memory non ecc
