With any system you will want to see a combination of synthetic testing and real-world. Synthetics give you a static, easily repeatable testing method that can be compared across multiple platforms. For our synthetic tests we use Everest Ultimate, Sisoft Sandra, FutureMark's 3DMark Vantage and PCMark Vantage, Cinebench as well as HyperPi. Each of these covers a different aspect of performance or a different angle of a certain type of performance.
Memory is a big part of current system performance. In most systems slow or flakey memory performance will impact almost every type of application you run. To test memory we use a combination of Sisoft Sandra, Everest and HyperPi 0.99.

Memory bandwidth is not too far off what we should be seeing with the memory we used here. The performance drops off during our OC testing due to having to use a more drastic divider to maintain stability.

Everest Ultimate is a suite of tests and utilities that can be used for system diagnostics and testing. For our purposes here we use their memory bandwidth test and see what the theoretical performance is.
Stock Memory Performance
Overclocked Memory Performance
Again we see the same memory performance we saw with Sandra. The drop during overclocking might come back to haunt us in other tests.

HyperPi is a front end for SuperPi that allows for multiple concurrent instances of SuperPi to be run on each core recognized by the system. It is very dependent on CPU to memory to HDD speed. The faster these components, the faster it is able to figure out the number Pi to the selected length.
For our testing we use the 32M run. This means that each of the four physical and four logical cores for the i7 and the four physical cores of the i5 is trying to calculate the number Pi out to 32 million decimal places. Each "run" is a comparative to ensure accuracy and any stability or performance issues in the loop mentioned above will cause errors in calculation.
Now, when you look at this chart you are going to think that the P7P55 WS is not a very good board for Hyper Pi. However, it is very important to note that the Xeon X3470 we used is running two 32M instances per core. That all by itself is extremely impressive, so those numbers are actually pretty good for the work load.
