Well like everyone else has already stated, a new CPU is in order here. But keep in mind that you want to have a system with a fast bus speed too. The P4 3.x Ghz cpu uses a 800mhz bus. That is pretty quick. I am not sure what the AMD chipset uses. Also, for best performance and compatibility, stick to the Intel chipsets. I believe the 865 has the 800Mhz bus speed. If you are leaning toward the AMD 64bit, you might want to see how it performs with your 32bit apps. Some 64 bit CPU's actually run 32bit code slower then a comparable 32bit cpu. I don't think that is the case with the AMD, but you want to get some benchmark comparisons with the apps you us if possible. Regards, Paul
