The other day, I bought a Pentium 4 3.2 ghz w/ HT. (1 GB RAM) I am a gamer and people are now saying to me that i should have gotten an Athlon64 or an AMD chip at least. What is the difference between a 32-bit processor and a 64-bit one? Isn't 3.2 ghz really powerful? And will 32-bit processors become obselete within the next 2 years? Because I am going to upgrade to an Athlon 64 3500+, but not for at least another 1 and a half years.
