How can I optimize my system? C2D, 975x premium, GF7900GTX, Win 64-bit...

Question

Hi, I'm pretty new to optimizing computers.  I have used Everest to get the following info on my systems performance.  It's a long text, but I'm uncertain as to what is important here...so bear with me.  Which values seem too low according to what should be expected(I'm not talking overclocking ... yet)?  How can they be altered?  A new BIOS version (running x64!)?  Any suggestions are welcome.  The system is stable.
