Personally, I cant stand MSI's web support, their site is riddled with errors, finding the downloads you need is unnecessarily difficult, and there's a lack of support for anything but windows.
I've just recently received my DFI board and havent yet entertained much of their support, however they're downloads are decidedly much easier to navigate too,IMO.
A note of caution though, my DFI Lanparty Ultra has a daughter board that is used for audio out and it's rather large. I had to dremel my 120mm fan to get them to fit together in the case. Also, if you're into legacy support, the DFI has no parrallel/serial connectors. Only pinouts for a COM port.
