Hi, I was thining of getting an Athlon 64 bit processor. I originally wanted a 3200+, but then I saw the 3400+ and the 3500+....Is there much of a difference between these 3 processors? There isn't a huge price difference, so I was thinking about the 3500+. By the way, I was thinking of getting either a K8n Neo2 plat. or an ASUS K8N-E-deluxe...Which mother board would you suggest? And why...THANKS!
