I got a Athlon64 3000+ for quite a good price (60% of new one). But in the system with 512 MB RAM. this CPU seems quite slow, I mean that the CPU usage is quite high( I never play game or application that takes all CPU power).Playing of an Divx file take about 25% of CPU.Is it normal due to the fact that the AMD speed is not high and decoding barely takes calculation.Or because Edonkey that always run sucks much of RAM
