SiSoftware Sandra (the System ANalyser, Diagnostic and Reporting Assistant) is an information & diagnostic utility. It should provide most of the information (including undocumented) you need to know about your hardware, software and other devices whether hardware or software. It works along the lines of other Windows utilities, however it tries to go beyond them and show you more of what's really going on. Giving the user the ability to draw comparisons at both a high and low-level. You can get information about the CPU, chipset, video adapter, ports, printers, sound card, memory, network, Windows internals, AGP, PCI, PCIe, ODBC Connections, USB2, 1394/Firewire, etc. Sisoft Sandra offers a variety of tests for Memory and CPU.

Again, the memory performance was better for the Asus P5E3 Deluxe WiFi. At the CPU tests, the P5K3 Deluxe is still a great performer. In some tests the P5E3 Deluxe WiFi was faster, that should be considered as an indication that both motherboards are really very good.
