when looking at mb now look at the number of ports on the back of the mb. also look at the ethernet chipset..higher end mb use intel ethernet chipset. for sound the entery realteck is the 8000 seri. the newer one is the 1100 chipset/
also look to see if it has the newer m2 sata slot. the newer m2 ssd going to be a lot faster then 6g sata.
