and about overclocking on the a64 fx-53: it is the easiest a64 to overclock. the non-fx series a64s have a multiplier lock, meaning you must increase the fsb to overclock. the a64 fx series does not have a multiplier lock, so all you need to do is increase the multiplier. good thermal compound will give you better temperatures whether or not you are overclocking. also, make sure that you are getting a socket 939 system as opposed to a socket 940, the s939 is both cheaper and a bit faster. (the s940 requires registered ecc ram)
