A question on memory chip specs.

I was looking at Corsair memory sticks at newegg, and I noticed something.

In the PC3200 512 MB, the sticks with a CAS latency of 2.5 were priced a couple dollars less than the sticks with a CAS latency of 3. $83 compared to $85. And the extreme speed sticks with a 2-3-3-7 and 2-3-2-6 latencies were much more expensive.

What is the practical difference between the 2.5 and 3 CAS latencies? Will I see it in overclocking? I want to run this 2500 at something over 2.00 Ghz clock speed.

I'm planning to get an Abit NF-7 MB, a Barton core 2500 XP AMD processor, and the PC3200 Corsair memory stick for 512 MB. Since the processor runs at 333 and the memory is at 400, will that be a good memory choice for overclocking? The 400 bus memory will run at 333 to match the processor?

    First off as far as memory bandwidth goes you'll be far better off to run the ram in sync with the FSB so that if the FSB is 180 the ram is also 180.
    For some reason you'll get better bandwidth that way (I have my theories on this but this isn't the time or place) and if you want to OC I'd suggest getting the tightest ram you can afford, the tighter the cas timings the higher the bandwidth is.

    Are tighter CAS timings higher or lower numbers?

    You're saying that I should get PC2700 memory since the processor has a 333 FSB?

    More details, please.
