Re: What is your view on the effect of DDR on system performance... Thanks for the kind words, you are overestimating me. :-) My personal WAG is a real improvement, but not a dramatic one. On the order of 10%. I haven't a detailed clock by clock knowledge of the interaction between the DIMMs, the chipset and the CPU like you do. I'm mostly going by the 4% to 5% improvement between 66MHZ and 100MHZ EDO and 3% to 4% from PC100 to PC133. Historically, a 50% increase in memory speed led to a 5% increase in performance, a 33% increase led to about a 3+% increase, so I'd exepect a 100% increase in memory speed to lead to a 10% increase in overall system performance. Of course, that's the difference in performance between a $500 CPU and a $700 CPU, so if it comes at little additional cost, it's a pretty big deal! Regards, Dan
