yeah m8,
the amd semprons are the low cost end of the cpu market like the intels celrons, but yeah the athlon xps are much better and cost virtually the same, the semprons are taking the places of durons, so yeah go 4 the xp much better,but if i was u i am going to buy athlon 64 because sooner or later the athlon xps are going to be replaced by the a64 but that wont happen for months years.
