I was wondering to all the people who have a rig similar to mine and have overclocked it, what did you think of the performance gain?  What settings did you do to O'C your components?  I would like to get liquid cooling but my case is to damn small.  but here is my rig;

CPU: AMD 4800+ Dual Core (939)
MB:   MSI Nvidia Nforce 4 Ultra
RAM: OCZ 2 gig of PC-3200 Dual Channel Platinum XTC
Video Card: BFG Nvidia 8800GTX
Sound Card: Crative Labs X-Fi
HD: 80gig WD Raptor 
       Seagate 320gig sata
Disk Drive: Lite-On sata DVD-ROM
                  Plextor PX-760A DVD-RW
PSU: Antec 550 watt NeoHE
Case: Antec P180
Cooling: Zalman cooling fans

I am looking to upgrade my PSU soon to a OCZ GameXstream 850 watts, so I have more power running to my computer and specially the graphic card.
