OK here I go again...(My wife just doesnt understand the need to upgrade!) Heres my mother board--- Its a u8668D Biostar.... I know its a 7.0 v or above by looking at the back panel. I'll find out exactly the version when I get home tommorow by looking at the guts!

My question is whats the differance in these CPUs? Also is the Celeron a POS when it comes to a processor for gaming? Any suggestions on a CPU? Its the kids game box. No internet at home.
