The reason CPU reviews typically show performance @ 1080p is that these resolutions tend to be most sensitive to CPU speed. At higher resolutions, the GPU becomes more of a limiting factor, and the difference between CPUs becomes a lot less.Their gaming benchmarks in the first slide show 1080p performance. Whos going to spend $500+ on a cpu and matching build for 1080p gaming? Show 1440p and above FFS.
In other words, it's just being done to show the CPU in the best light - not because they actually expect people buying an i9 to run at only 1080p.
