It's for a 64bit gaming system sorry.Little if any oc'ing

 

[(cf)Eclipse]

an a64 then?

if you don't plan to oc much, if at all, there's no point in getting anything rated above pc3200

that stuff is awesome, plus is can take 3.2-3.4v with a fan on it for when you do want to get into oc'ing. a few guys around here use it in their rig

 

[jml90]

But would the other stuff you recomended be an better?

 

[(cf)Eclipse]

well if you wanted to oc, the other stuff is gauranteed for 233mhz, while the cheaper twinmos is only 200mhz. that's really the only difference between the two
