Having only been seriously into computers for about a year, I have gained so much knowledge...however there is one thing I've never understood. Whats the difference between the AMD Athlon 64 line of processors and the AMD Athlon FX line? Both are sockent 939 and both are 64-bit. Why does the FX line cost so much more than the regular 64s? And I remember watching "The Screen Savers" and them saying that the FX line doesn't offer enough performance than the regular Athlon 64 to justify the extra cost. Excuse my ignorance and noobiness, but I have always wondered this.
