You have written "for graphics, sound and price"
Does that mean you want onboard graphics or not? Because some of the mobo's listed don't have onboard graphics.
Anyways, if you want onboard graphics nothing beats the Asus A8N-VM CSM GeForce 6150. If you don't want onboard graphics, get the Asus A8N-E.
ASUS A8N-E does not have an IGP...and is a little expensive.....than ASUS A8N VM CSM.....it has a IGP and .....the IGP 6150 is quite good....infact the one of the best IGPs around for that amount of money......u can play all games at low-mid setings....
