Which is faster?

[Whidbey]

Which would give you a better performacne boost, a low memory cas latency of say 2, or overclocking your cpu's clock speed and a lower cas of say 3?

Your question makes no sense. Please rephrase.

-edit-

Ok thats better.

Your cpu being overclocked will give you the biggest tangible difference.

The lower the timings/latency on the memory, the better the performance coupled with the oc but since you are going out of spec, you will have an increased liklihood of system instability.
