WorldBench 5's Photoshop 7.0.1 module should be another area where system memory bandwidth plays a factor alongside CPU performance.  Let's have a look.

PC World's World Bench 5.0: Photoshop 7 & Windows Media Encoder Image Editing and Digital Video Encoding

Here it's a virtual dead-heat between the P5ND2-SLI Deluxe and the reference NF4 SLI Intel Edition board.  The Athlon 64 system takes first slot however, with a measurable 14 second time advantage.  From there the numbers speak for themselves and the rest of the pack is tightly grouped together performance wise.

Windows Media Encoder 9 is both SSE optimized and multi-threaded, so we'd expect the Pentium 4 based systems to have an advantage in this test.

In this benchmark we see the antithesis of what we saw in the Photoshop 7 test.  The Athlon 64 4000+ falls in behind the slowest Pentium 4 EE 3.73GHz score by a large 54 second deficit.  From there the rest of the data seems to scale accordingly, with the P5ND2-SLI Deluxe neck and neck with our NVIDIA reference board.
