i have similar config, my board is MSI K9NGM, i am not able to find the linux drivers for the on board Ethernet Vitesse VSC8601 and for the sound drivers as well. i just upgraded to this config so i am not yet sure of the performance and also i couldnt really test my system cos i dont have these drivers, http://www.msi.com.tw/program/support/driver/dvr/spt_dvr_detail.php?UID=734&kind=1
this link only provides drivers for Windows OS, not for Linux, if anybody can help me out, i would really appreciate your help....
