For all we know, a dual core chip will work the same. At one point, a MS executive stated that Hyperthreading would not work with Xp Home, but MS later retracted that statement. So that is an excellent catch by you . http://www.eweek.com/article2/0,3959,524969,00.asp Interestingly, some of the dual core Intel chip will also support hyperthreading. So would it may be possible to run 4 threads on dual core HT enabled unit on Xp Home and with 8 threads on a dual processor, dual core HT enabled ?? Best, Michael
