I bought the Gigabyte MA790X-UD3P, which is a DDR2 version of the same MA790X-UD4P (DDR3) model. The mobo has 2 PCI slots, altho I don't think I'll use them really. These mobo's are made for AMD processors, but I'm sure Gigabyte offers something similar for Intel as well. I'm not sure about other brands, but Gigabyte seems to continue to implement PCI in some of their mobo's. Not extinct yet. ;)
