AIDA64 Extreme Edition TestsAIDA64 Extreme Edition is the evolution of Lavalys' "Everest Ultimate Edition". Hungarian developer FinalWire acquired the rights to Everest in late November 2010, and renamed the product "AIDA64". The Everest product was discontinued and FinalWire is offering 1-year license keys to those with active Everest keys. AIDA64 is a full 64-bit benchmark and test suite utilizing MMX, 3DNow! and SSE instruction set extensions, and will scale up to 32 processor cores. An enhanced 64-bit System Stability Test module is also available to stress the whole system to its limits. For legacy processors all benchmarks and the System Stability Test are available in 32-bit versions as well. Additionally, AIDA64 adds new hardware to its database, including 300 solid-state drives. On top of the usual ATA auto-detect information the new SSD database enables AIDA64 to display flash memory type, controller model, physical dimensions, and data transfer performance data. AIDA64 v1.00 also implements SSD-specific SMART disk health information for Indilinx, Intel, JMicron, Samsung, and SandForce controllers. All of the benchmarks used in this test- Queen, Photoworxx, ZLib, hash, and AES- rely on basic x86 instructions, and consume very little system memory while also being aware of Hyper-Threading, multi-processors, and multi-core processors. Of all the tests in this review, AIDA64 is the one that best isolates the processor's performance from the rest of the system. While this is useful in that it more directly compares processor performance, readers should remember that virtually no "real world" programs will mirror these results. 
The Queen and Photoworxx tests are synthetic benchmarks that iterate the function many times and over-exaggerate what the real-world performance would be like. The Queen benchmark focuses on the branch prediction capabilities and misprediction penalties of the CPU. It does this by finding possible solutions to the classic queen problem on a chessboard. At the same clock speed theoretically the processor with the shorter pipeline and smaller misprediction penalties will attain higher benchmark scores. Like the Queen benchmark, the Photoworxx tests for penalties against pipeline architecture. The synthetic Photoworxx benchmark stresses the integer arithmetic and multiplication execution units of the CPU and also the memory subsystem. Due to the fact that this test performs high memory read/write traffic, it cannot effectively scale in situations where more than two processing threads are used, so quad-core processors with Hyper-Threading have no real advantage. The AIDIA64 Photoworxx benchmark performs the following tasks on a very large RGB image:
As you might expect with three motherboards running the same chipset and processor, the performance results are very close, with the MSI motherboard running just a few percent behind the Intel and ASUS motherboards. The Intel and ASUS boards post scores within a fraction of a percent of each other. 
Overclocking buys us 21% improvements in both ZLIB and Hash (the ZLIB results don't look as impressive due to the scaling of the chart). The AES test shows virtual parity between all platforms, although going by the numbers the MSI motherboard wins this one. Oddly, overclocking the ASUS motherboard lowers the score very slightly. 
Let's move on to the PCMark 7 benchmark.

Comments
1. Most people only boot their systems once a day, if that, and the time spent to get to the Windows desktop is insignificant compared to the time the computer's being used.
2. The time will vary greatly depending on the boot device (regular hard disk, Velociraptor, SSD); the version of Windows being booted, drivers, etc.
Granted, you could use a standard hardware configuration and Windows installation to reduce the number of variables in #2, but I don't think that many people would find it useful. FWIW I didn't notice the board being particularly speedy or slow.
For reference try googling it and see dozens and dozens (hundreds even?) of people on tech forums around the world trying to find this information out :).
Or head over to anandtech and see how almost all of the positive comments mention POST time benchmarking as a great review feature.
As to hardware variability, I would assume by now that any enthusiast knows that overall boot time is greatly effected by hardware, most notably HDD/SSD. However POST time can still make 20 seconds of difference in startup time, considering most machines with SSDs start up in well under a minute, you can see how a lot of everyday users would like to see how they could shave most of this time off.
Once again, thank-you for the great review and for the reply :).
If you want a fast bootup: you should disable all of the motherboard features you don't use, use a small and fast boot device like a SSD without RAID, and don't install drivers and services unless you absolutely need it.
