What RAM?

[GunnerMan]

Well I am looking to upgrade my ram. I am in the 120 price range for 1 512 stick with TCCD chips. A while back people told me to get at least PC-4000 even if my board only supports PC-3200 because it allows for lower latenceys and better overclocks, is this true? I found these two are they good? Thanks
