mySQL Load! Please Help!

Hello,

mySQL on my server is using 50% of the CPU at least and I have found in the Apache/mySQL CPU usage feature of WHM that its the top process and it uses about 190+ of ram.

::Server Specs::
P4 2.4 Ghz
1 GB DDRam

::mySQL my.CNF File::

Okay now about the sites.

We host a lot of forums, 40-50 small forums, 5-10 medium forums ( ipb and phpbb ), 1 big forum ( 70 gb / month bw usage )..

And we host a site that has a game which requires communicating with mysql frequently, like updating battle records in a second, or retrieving the records in a few more seconds etc..

So i would say, mySQL is used a lot. Apache also uses 20-40% almost all the time.

Can anyone help me with quick optimization of the mySQL. I am not any expert at mysql configurations, although i tried my best, i wasn't able to optimize it. I would really be grateful if someone can help me out here.

Thanks

 

Anyone ????? *BUMP*
