Computer Performance downgraded significantly

[MasterZonk]

Just swapped out a motherboard, the old one fried. Now that everything is running, I'm noticing extreme differences in games and such, i can't even run some of the games i used to be able to run perfectly. is a problem with a part, or something else. Help!
