Content Creation Winstone 2004 is a system-level, application-based benchmark that measures a PC's overall performance when running top, Windows-based, 32-bit, content creation applications in Windows XP.

Business Winstone 2004 runs real applications through a series of scripted activities and uses the time a PC takes to complete these activities to produce its performance scores.

In both benchmarks, the Chaintech Zenith VNF4 Ultra performs near the front of the pack. Since both these benchmarks are workstation oriented, I doubt end users would notice any difference between the fastest and slowest machines.

HDD performance is the same as the other nForce4 motherboards tested with the WD Raptor. Graphics WinMarks are nice and high.
