AMD Am486 DX4/120

One of the faster 486 processors. The 120MHz model is up to speed with it's 40MHz front side bus (FSB). Unfortunatly the 40MHz FSB is not always a big improvement over the 33MHz FSB depending on your motherboard. In my case the DX4/120 doesn't run Doom faster than a DX4/100 because the PCI bus is clocked lower when using the 40MHz bus due the nature of the dividers. This affects Doom quite a bit as seen in the benchmarks. Other benchmarks, especially those that don't use the PCI-bus much, run a lot faster :).
