I plan to over clock a E8400 on a X48 board...and I am trying to see which of these will be best? I heard 1066 is a buffered 800 for DDR2...is there any benefit to buying 1066 over 800 at this point? The price difference between them isn't an issue for me. The motherboard is LANPARTY DK X48-T2RS http://www.newegg.com/product/product.aspx?item=N82E16813136047
