Loz, from what I see it looks good, I agree with what bob said, run prime blend for 2 hours to establish stability, if it fails, ie lost worker, freeze or BSOD add more Cpu Voltage until it passes. Keep the temps below 70 on the Cpu and 62 on the package and you good.
As far as performance testing for what you use it for only you can tell that. You can use synthetic benchmarks to test as well, but real world usage will be the true test.
