This is a good processor and manages multi tasking and heavy load without issue. Easily over clocked and I've had it up to 5GHz quite nicely with a max temperature of 72C. A nice piece of kit. They could save you a bit of cash if they had done away with the poncey packaging, but even that was good.

Wow very fast.

Superb, auto boosting clock speed from 3.6 to 4.7GHz without overclocking.

Great processor the best in fact, but like every high end component it comes with diminishing returns highest end products are never good price/performance ratio but thats not a negative for the product as most people would have you believe, as its the same for any product.

I have been using CCL for 20 years nearly. I have always found the staff helpful kind and considerate and very in tune with my needs and its always a pleasure dealing with their staff. I always Collect in person too as being semi local ( 20 min drive) and sometimes find me having a natter or just oogle with some of their gaming pc displays etc.
