What is CAS latency? What does it do? I am looking at some Mushkin RAM to get. It seems that the latency is what causes fluctuations between the price on products between the amount the RAM is (256MB vs 512 MB). I'd also like to know if 2x256MB is good or if I should get 2x512MB. If anyone knows of any good deals on going, or of better memory please feel free to enlighten me.
