Re: five-year-old silicon obsolete?
"The only reason i might upgrade a motherboard/processor now is to reduce the power consumption for the same tasks, if that is possible."
Exactly my situation. I long for a fanless quad ARM device that is comparable to my 10yo core2quad. I have no need for more oomph, what I want is something with no moving parts, has near-zero energy costs, and fits on the back of my monitor. It would be nice, but not required, if it also had some chip level opcodes to give me a zippy dosbox. At that point I have zero use for MS, AMD, Nvidia, and especially Intel.
