the MSI neo 4's have a great audio chip, if you want something better than the rest. if you have a PCI soundcard tho, don't bother. the dfi ultra-d can be easily modded to support SLI and SATAII. the dfi is very, very picky when it comes to RAM, esp. value RAM. also, you must use a native 24-pin PSU with it. for you, i'd suggest the asus, like Bateluer.
