Re: I Need Professional Opinions on Processors!!
What do you want to use your computer for?
For gaming and graphics stuff, get the AMD 64 like darkblade says.
If you are more into video editing however, I would go for an Intel processor and MB as they are considerably faster at this function (try a P4 550 with a 525 chipset MB).
