I'm on my way of upgrading to the athlon 64's and I'm a little confused as to which processor is better . . . the 4600+ (Windsor - 90nm, energy efficient) is at 2.4 Ghz while the 4400+ (Brisbane - 65nm, energy efficient) is at 2.3 Ghz. Which is the better processor? I think i have the general idea that the newer 65nm technology is better than the 90nm, and the 4400+ is a few bucks more expensive than the 4600+ on newegg, but I'm still not quite sure which is truly better between the two. Any shed of light on this would really be appreciated. Thanks.
