• <!-- start ziffpopup //-->Dell OptiPlex 755's test scores.

• WorldBench 6 Beta 2
• It produced poor scores in our graphics tests, but that's to be expected on a PC  with integrated graphics, as is common on business desktops
• environmental performance tests, which are not yet part of our PCW Ratings, the  OptiPlex drew less power than any other desktop or notebook

• PCMark assesses the machine's overall performance with specific scores given for  CPU, memory, graphics and HDD
• PCMark assesses the machine's overall performance with specific scores given for  CPU, memory, graphics and HDD; this gives us a useful indicator of performance  dealing with typical office tasks.
• 3DMark and Cinebench are indicators of the machines graphics capabilities

• 3DMark and Cinebench are indicators of the machines graphics capabilities. We  also use Sandra Pro to give some specific figures on processor, memory and drive  performance. Usability issues include location (and type) of ports and buttons  as well as additional software utilities. Construction elements of interest are  case material quality and ease of opening for maintenance and upgrades. Sound  quality is also considered along with the software included with the  machine.

• Windows Vista scores the OptiPlex at 3.4 overall, but given that this machine is  really intended for an office environment, the relatively low games graphics  score and even the Windows graphics score is relatively unimportant. (The  overall score given by Windows is simply the lowest component score.) The  OptiPlex scored 5.5 for CPU performance, 5.9 for RAM, 3.7 for standard graphics,  3.4 for games graphics and 5.5 for HDD performance.
