Timings vs. FSB/Memory Ratio vs. MHZ

[Operaghost]

Basically, I'm confused on what RAM to get because I don't know exactly how I want to OC the rig I am building:
P4 2.4c
Abit IC7
Visiontek X800 Pro
Zalman 7000Cu
WD 74gig Raptor

Now this is my dilemma. This rig is purely for gaming. Thus I want optimize the overclock for just that. However I am confused as to what would give me better results in games. Would having the highest CPU speed possible be best? Even if it means compromising my memory speed to run in 5:4 ratio? Or would I have best performance in REAL world gaming from having the tightest timings possible on my RAM even if this means only running 220ish FSB, as opposed to possible 250-270?
I've read "THE Memory FAQ" so don't point me there. While it was very informative I still wasn't able to answer these questions. Any advice? Suggestions? Please backup any theoretical opinions with reviews/benchmarks of some kind.

This article should give you just a bit more info then the FAQ

Wow thank you. Looks like that pc3500 EB from OCZ is some good stuff if you're going up to 250 FSB. Thanks, I just may purchase those.
