I found this website helpful in optimizing my own mysql server: http://www.omh.cc/mycnf/

It allows you to tune your variables and know what the total ram capacity will be. You need to optimize for 60% ram usage. So try to lower your total memory footprint to about 60% to 70% of your total ram. If you have other stuff running on the same machine, you probably need to reduce that number. Forget Query cache, it's not going to add too much value, but Table cache should improve your performance if done right.

Try reducing the number of connections and keeping your total memory footprint under 60% of total system memory.
