Which standard is that? Only the very top of the line Intel i5 and i7 CPUs can make good use of triple channel RAM, so how can you affirm that this is a new standard? Olny if you are talking about extreme PC blogs/magazines and websites and such. Because outside of this little enthusiast niche, 6GB of triple channel RAM is HARDLY any sort of standard. Heck, I'm yet to see any kind of game or domestic application which can be bottlenecked by 4GB of DDR2 1066Ghz RAM.
Having 6, 8 or 12GB of RAM only for gaming, is like having 4x5970 GPUs crossfired to run games at 1280x1024. A pure waste of money, space and power.
