AMD Opteron 150, 2.4GHz, Socket 939, 1MB, BOXED w/fan £240

AMD Opteron 154, 2.8GHz, Socket 939, 1MB, BOXED w/fan £690 maybe not that one lol

im debating over the 150 or 170 not sure if i want to go dual core again , 150 looks good as i stand better chance of making 3g

im assuming there all multi locked or do some have unlocked multis?
