Well, I have basicly that same asus mobo you listed just an earlier version and its really good (i'm an asus fanboy personally
). The only problem I had was that the crappy heatsink fan didn't work right so I had to replace it (lots of people had that problem). The DFI one looks good however, the reviews do say it is a pretty advanced board to use (that probably won't be a problem). Both boards look good buys to me. The asus one is a little cheaper but than fan can be a real problem. They are both good boards but the DFI seems to be the one for you, more of an enthusiast board. Great for overclocking and stuff. Im not sure about the lan drivers, does it really matter?
