Is this memory any good?

[dave8624]

I am a n00b and don't really get the whole latency thing so if you can tell me which is better I'd appreciate it.

Patriot Extreme Performance PC2-6400 @ 5-5-5-12 2x2Gb
OR
OCZ w/ Platinum Heatspreader @ 5-4-4-18

Basically what is the difference in the latancies?

Is 4-4-4-12 better than 5-5-5-12?

Sorry for being such a n00b. lol.
