DOug, on FSB vs memory speed. With 200 MHz FSB, DDR PC2100 memory (the 133 MHz kind) has more bandwidth than the CPU to memory link by about 33%. Therefore, the only use for the extra memory bandwidth is for AGP (memory to graphics board) transfers. The situation is even worse with the P3 133 MHz bus and DDR PC2100 memory because the memory bandwidth is twice as high as the CPU can handle. With a 266 MHz bus, the peak memory bandwidth is exactly equal to the peak CPU bandwidth. There is also DDR1600 memory (1600 MBytes/sec), but I think the 2100 variety (2,133 MBytes per second) will be nearly the same price and more widely available. Petz
