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 3D Mark 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 of flaky 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.

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.
First off in Everest compared to the M3A790GX/128H we see that at stock speeds, both boards perform identically. Overclocking wise, we managed to get a better result out of the newer 785G.

Again with synthetic memory performance we get the new 785G board in front especially when overclocked.

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 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.
Running HyperPi with all four cores in use, we came in with just over 20 minutes. When we overclocked the CPU we managed to reduce this down to over 18 minutes - this is quite good for this type of CPU.
