Office Application Benchmarks
With enabled 'super bypass' Irongate scores identical to KX133. AGP-performance and memory bandwidth have little to no impact on office applications, as already mentioned in the initial KX133-article.
Those results were run with the new NT-driver for GeForce, described in the first addendum to the KX133-article . As you can see KX133 has still got a slight edge over Irongate with enabled super bypass, but S/B does definitely make a difference here.
