MOTU 2408 Core MkIII PCIe vs. EMU 1616m PCIe

My EMU 1616m PCIe just died. I need 6 analog audio outputs to monitor surround sound 5.1.

I’m running on XP64 and I’m pretty sure want to use my PCIe slot (vs. the available PCI slot). Will the extra bucks for the MOTU be worth it, or should I just get another EMU 1616m PCIe?
