i bought a dual-core amd 3800 and it came with vista operating system and one gig of ram. I loaded nero and started a transcode from avi to dvd (dont remember format) and i was exspecting like maybe double the speed of my single core laptop amd 3400 with xp home with one gig of memory and to my surprise the dual-core was twice as slow. hmmmm what gives?? I did a control alt delete and checked my cpu usage and it was at a 100percent with the new system. Anyone with any input on this???
