Not a huge difference but still noticeable within Business Winstone.  Shifting gears to another PC Magazine Benchmark we find Content Creation 2004.  PC Magazine's Content Creation 2004 is another suite of office apps but it focuses more on design and creativity.  The programs run to generate a final score as shown below are Adobe® Photoshop® 7.0.1, Adobe® Premiere® 6.50, Macromedia® Director MX 9.0, Macromedia® Dreamweaver MX 6.1, Microsoft® Windows Media™ Encoder 9 Version 9.00.00.2980, NewTek's LightWave® 3D 7.5b and Steinberg™ WaveLab™ 4.0f.

Again, a noticeable but not a huge performance difference with the graphically intensive Content Creation. 

Next up is SiSoft Sandra 2007 Pro with their CPU Arithmetic Benchmark and Multimedia Benchmark.  With the same processor and graphics card in both systems we don't expect much difference but its about how well each system can get the rubber to the road as well.
