I am needing to upgrade my old Dell system, a Piii 450. I think I'm finally ready to plunge into building my own system, but need to do it cheaply. Some has a used Asus a7v8x available. This is the original, not one of the newer -X boards. What am I giving up by not buying one of the new boards? Since I'm not an extreme gamer, I don't have huge requirements for OC'ing. Thanks.
