As i type away on my quad core processor with its eight threads i can somewhat feel that a bit of light word processing isn't really pushing its power to the max. Obviously when i need its four cores for some video rendering or photo work, it's ready and waiting. Not everyone needs that amount of computing power though, and it would simply be money wasted.
This is why AMD have continued to keep focus on dual core processors, but have still been squeezing higher clock speeds out and coming up with the the AMD Phenom II X2 555 dual core 3.2GHz AM3 processor that we're looking at today. Also, did we mention it's part of the Black Edition range?
