The Core2 Quad Q6600 is over 7 years old which is a lot of processor lifetimes! This particular model has been included in the group test simply as a reference because of its exceptional popularity back when it was at the forefront of technological advance. The Q6600's four physical cores demonstrate exceptional overclocking capacity and often achieve in excess of 40% performance increases. Modern Quad core processors offer nearly three times more performance on both single and multi-core workloads. There have also been lots of non-processing related improvements in the platform over the last 7 years which include SATA 600 MB/s, USB 3.0 PCIe and more. [Mar '14 CPUPro]

The Intel i5-4440 is one of the cheaper four core Haswell processors. Unfortunately it is clocked at just 3.3 GHz Turbo, which is 15% lower than the leading Haswell i5 and because it has a locked multiplier there is little that can be done about it. Comparing the 4440 to the 4670K shows that the 15% reduction in Turbo clock speed basically results in a 23% performance loss to the 4670K. The Pentium G3420 actually has a higher base clock speed and costs about a third as much as the i5-4440 yet for the majority of, single and dual-core, desktop orientated tasks offers comparable performance. I don't think the i5-4440 makes much sense and would prefer either a much stronger 4770 or the weaker but much better value G3420[Mar '14 CPUPro]
