You upgraded from an Athlon 64 X2 4200+ !!!! I'm jealous (writing this on a 900 Mhz P3).I really haven't noticed much of a difference. I am sure if I did certain things like video encoding, or played games more I would notice. I am a computer enthusiast, was single at the time, and no kids. So I have money to burn.Did you actually see any increased performance? How much? Just curious.
The X2 4200+ came to work, and is what I am typing this from.
