Skulltrail is still the fastest PC for rendering and video editing and we've heard it's even selling well with Red digital HD cameras, as it’s the only PC which can give enough encoding power to this semi-professional HD film camera.
Intel already said that this year's Skulltrail is not the last one and that you can expect one based on Nehalem. Of course, we are talking about insane two sockets and sixteen threads from two Xeon-based Nehalem EX CPUs.
We don’t know when this crazy PC will be ready, but you can count on the fact that it will be the fastest and probably the most expensive thing around. Most of the today’s applications won’t be able to cope with such a raw power, but you will at least know that your PC is the fastest one on the block.
