Secondly the CPUz screenshots might show high clock speeds, and indeed they do, but the actual benchmarks don't remotely echo the expected level of performance.
I don't think any of the drawbacks are serious, except for maybe the temp sensor which is an inconvenience. I only know of one game - GRID 2 - which can use AVX extensions, and as for the iGPU/c-states etc. etc. - I wouldn't be unduly bothered.
