Hello, Dan ! You may be right with your assumption, 266MHz FSB will boost overall performance by 10%. Within the hierarchy of memories, the HDD is the "caboose" of the system. If the operating system does does not access the HDD while performing a calculation, then the access to the DRam is the main impact on the performance (Linux OS f.e. accesses the HDD very rarely). From an Excel-sheet, which I put up last year, the rough "calculation by thumb" shows an increase of about 90% in performance (FSB 100MHz compared to 266MHz), when only cpu-registers, L2-cache and FSB are invoked. But nevertheless the FSB stays the bottleneck of the system, therefore new architectures like "Infiniband" are under investigation. If I should have overseen something, please feel free to discuss it! CU Mapolo
