PCMark Vantage => 15310
Core i7-875K already has very high performance at default clock as with Turbo Boost OC technology.
As per CPU utilization rate, the clock will be in between 2.93~3.60GHz. It should be affordable for most application.
Sandra Memory Bandwidth - 19460 MB/s
EVEREST Memory Read - 14717 MB/s
Even though LGA 1156 has dual channel structure, not like as triple channel in LGA 1366, so the DDR3 bandwidth is lower.
Core i7 CPU built-in Memory Controller design makes LGA1156 DDR3 bandwidth be higher than dual channel PC platform over 1.5 times more.
PSU is be quiet! latest power4 DELUXE 530W which is high C/P value product.
100% Japanese solid capacitors, 12cm low acoustic fan, 2-way 12V output designs.
In this CPU Core i7-875K and VGA HD5830 platform, it can adequate OC or high loading system.
530W is also enough for ATI CrossFireX

3D gaming performance is relied on VGA capability.
However, the higher performance CPU can enhance 3D performance around 10-20%.
Core i7-875K performance is quite high standard, so when you use with ATI HD5380 for better 3D.
Temperature
Stnadby - 37~40
CPU Full Load - 53~59
Intel Burn Test v2.4,Stress Level Maximum
Under room temperature is 28℃, CPU full speed is still lower than 60℃.
For 4C/8T spec, Core i7-875K temperature is very good.
