I just found this board, after some searching earlier, seems to support everything except 3 x DDR400 slots, is it any good?

However, users must take note that the ASRock 775Dual-VSTA (VIA PT880 Ultra) is an AGP chipset with PCI Express support and not the other way around. Therefore, it carries a full AGP 8X interface, but limits PCI Express to four lanes. As such, the PCIe x16 slot on the 775Dual-VSTA is actually only capable of running at PCIe x4 electrically.

i was also thinking of getting a x1900xt card with this will pcie 4x impcat on the performance of this card much?
