So..about that overlocking..

Just looking for some opinions and advice of people of know more than I do about OC. I know a fair amount about it so don't be afraid to get too technical. I just want to see how fair mine could really go! (apart from gaming and everyday use.) Also, I understand that no two setups, even identical, could or will produce the same results. Thanks!

My setup:
Intel i7 920 d0 @ 2.66 ghz @ 1.216(gotten it up to 3.8 without having to adjust CPU voltage)
ASRock X58 Extreme Mobo
MSI Radeon HD 6950 OC Edition
6 gb Kingston T1 Hyper X 2000mhz RAM
600w OCZ PSU
64gb Patriot Torqx 2 SSD
1 TB Hitachi HDD
A few lights here and there....

Ive messed around with settings a little and read a ton of stuff on my MOBO and CPU. Im more interested in OC the CPU, but i assume to run that at the highest your DRAM should be adjusted accordingly. Thanks in advance!
