Processors

Because we over clock all water cooled systems as standard unless asked not to the stock CPU speeds are a little irrelevant. At the same time the “Water Cooling” option has a bearing on how much we can safely over clock a CPU. It is easier to discuss each systems potential individually however a 965 won’t necessarily obtain a higher over clock than a 920 as other factors have to be taken into account.

For example in a Lian Li case with full chipset/mosfet cooling a 920 CPU will happily run at 4.2GHz, however an identical system but with just CPU/GPU cooling 3.7GHz is a more realistic speed as the chipset cooling is limited on air.

Intel® Core™ i7

With faster, intelligent, multi-core technology that applies processing power where it's needed most, new Intel® Core™ i7 processors deliver an incredible breakthrough in PC performance. They are the best desktop processors on the planet.

You'll multitask applications faster and unleash incredible digital media creation. And you'll experience maximum performance for everything you do, thanks to the combination of Intel® Turbo Boost technology and Intel® Hyper-Threading technology (Intel® HT technology), which maximizes performance to match your workload.

Go to the next level of multi-core performance.

Intel Core i7 processors deliver an incredible breakthrough in quad-core performance and feature the latest innovations in processor technologies:

Intel® Turbo Boost technology maximizes speed for demanding applications, dynamically accelerating performance to match your workload—more performance when you need it the most.

Intel® Hyper-Threading technology enables highly threaded applications to get more work done in parallel. With 8 threads available to the operating system, multi-tasking becomes even easier.

Intel® Smart Cache provides a higher-performance, more efficient cache subsystem. Optimized for industry leading multi-threaded games.

Intel® QuickPath Interconnect is designed for increased bandwidth and low latency. It can achieve data transfer speeds as high as 25.6 GB/sec with the Extreme Edition processor.

Integrated memory controller enables three channels of DDR3 1066 MHz memory, resulting in up to 25.6 GB/sec memory bandwidth. This memory controller's lower latency and higher memory bandwidth delivers amazing performance for data-intensive applications.

Intel® HD Boost significantly improves a broad range of multimedia and compute-intensive applications. The 128-bit SSE instructions are issued at a throughput rate of one per clock cycle, allowing a new level of processing efficiency with SSE4 optimized applications.
