Our first benchmark - Cinebench - concentrates on the multi-core performance of each system's CPU and it paints an interesting picture.
The pre-overclocked hexa-core Core i7-3930K in the Scan and Dell systems leads the pack, but the quad-core Core i7-3820 in CyberPower's Infinity Xtreme XT is some way behind. Going by these results, the cheaper Sandy Bridge Extreme chip offers little more than a heavily-overclocked Core i7-2600K.
But benchmark scores aside, let's not forget the obvious; all of the above-featured CPUs are blazing fast.
Geekbench assesses combined CPU and memory performance, and the quad-channel architecture of Sandy Bridge Extreme allows the CyberPower system to sit comfortably near the top of the charts. It is a very-fast machine and by using a SATA 6Gbps SSD as the default system drive, it's ultra-responsive, too.
