Hi guys i know i have asked many dumb question before but her i go with another one......... how much better is ddr ram over pc133 ram? if i can get 512 of pc133 is it as good as 256 of ddr? i found 512 of pc133 for $36 and 256 of ddr for $72. i can use either being that i havent built the computer yet. the memory is what is puzzling me. depends on what memory depends on what board i get.

thanks guys!
