<div dir="ltr"><div>Thank you Axel. Your advise rises another doubt. Can we get the maximum performance from a highly clocked CPU?<br></div>I used to consider that the the fastest CPUs were too fast for the memory access, resulting in bottlenecks. Of couse it depends on cache size.<br>
<div><div><p dir="ltr">>Stick with the cpu. For QE you should be best off with
intel. Also you are likely to >get the best price/performance ratio with
CPUs that have less than the maximum >number of cpu cores and a higher
clock instead. </p>
