(FVM doesn't really benefit and LBM still has a long way to go.) @Eakarach: Of course they don't scale lineary, but it is not nearly as bad as you describe. And what...

If you use the same cpus as ghost82, that would mean 8cpu*150w/cpu*1,25=3000W. Most cpus use less power than their TDP, due to the...
