Hey guys, I have a computer waiting to be boosted through some nice overclocking.
Running in my rig now is:
CPU: Intel Core 2 Quad Q9550 @ 2.83GHz (under water

)
GFX: ASUS HD 5850 (went for the one with better stock cooling, this beast is made for overclocking)
MOBO: P5Q3 Wifi-Deluxe
RAM: G.SKILL Ripjaws 8GB (2x4GB) DDR3 1600 (pc3 12800)
(timings are 9-9-9-24, stock.)
Just got the RAM in today, and have decided that I'm not going to wait to buy a SSD before I start my overclocking adventure. Not that it matters... 
My question for you guys is this: What do I start with? I know I can find lots of articles out there on HOW to overclock (I know the basics, and will gladly do the research and learn more). I just haven't been able to find a site that tells you WHAT to start overclocking first. I take it I want to OC something, get it stable, and then move on... but is there a chance that I would get higher clock speeds by having other components running faster too? Does that mean that I overclock an item, move on, and then come back to it to see if I can get a bit more juice out of it?
Thanks for the replies. This is my baby, I want to do this RIGHT!
