i have researched the lowest offered core x2 processor that AMD offers, and for now, i truly do not think it is worth it - the 3800 x2 is the cheapest one and comparing with the regular, single core, 3800 i could not see a lot of benefits from switching to a dual core - the 3800 single core simply wins about 70% of the benchmarking tests - and the other 30%, well....it seems to be that the x2 is geared more towards business type application multitasking
...if you ask me...the 3800 single core is LOOOOT better buy
