O que a maior parte do pessoal que já anda neste mundo à uns tempos vai responder será:
Investir numa tecnologia/equipamento acabado de sair é completo desperdício de dinheiro, pois algumas semanas após o lançamento os preços já estão completamente diferentes. Isso para não falar que são tecnologias que ainda não tem provas dadas.
Isto para responder a estes últimos posts.

Pelo menos inicialmente, só haverá Nehalem para servidores single ou multi-socket, e para desktops high-end (single ou dual-socket, A.K.A. Skulltrail 2 ).Alguém me pode esclarecer sobre se os novos processadores core i7 estarão disponíveis nos computadores portáteis? Se sim, em que data estarão disponíveis?
"But programming in parallel is simply too complex for the average code writer, who has been trained in a very linear fashion. In conceptual terms, traditional coding could be compared to a woman being pregnant for nine months and producing a baby. Parallel programming might take nine women, have each of them be pregnant for a month, and somehow produce a baby."
" 'If I were the computer industry, I would be panicked, because it's not obvious what the solution is going to look like and whether we will get there in time for these new machines,' says Kunle Olukotun, a computer science professor who is attacking the multicore challenge at Stanford's new Pervasive Parallelism Lab. 'It's a crisis, and I wonder whether what we are doing and what is happening within the industry is too little, too late. . . .' "
The use of chips with four cores in the past year has meant that such a PC today is no faster for many key tasks than, say, a comparable computer purchased three years before. Worse, with chips of six or more cores on the way, your favorite applications could actually run more slowly.
What would probably make more (though still not much) sense is to have an OS that could intelligently give programs and/or major subfunctions their own CPU rather than make them share.
O novo processador Core i7 irá chegar ao mercado nas primeiras duas semanas de Novembro, sendo que o modelo mais rápido irá operar a 3.2GHz e terá um preço de $999 dólares.
O mais acessível de todos será o modelo de 2.66GHz que deverá custar cerca de $300 dólares e até ver só a Intel tem um chipset pronto para receber os seus próprios processadores. O Nehalem parece estar em grande forma, e espera-se que seja possível atingir grandes resultados ao nível de overclocking e performance de processamento.
We were surprised to see that the Bloomfield generation of CPUs will officially support DDR3 800 or 1066. Even the extreme edition 3.2GHz Core i7 officially only supports DDR3 1066 and not faster. There won't even be an official support for DDR3 1333 not to mention 1600 or faster.
Fudzilla has already mentioned the fact that for some reason you need to run memory CPU voltage synchronously which might be an overclocker's worst nightmare. At this current stage you cannot go over 1.65V and some memories such as DDR3 1600 or DDR3 2000 might need a bit more than that. With more than 1.65 you will kill any current Nehalem CPU.
Bloomfield Nehalem doesn’t run with DDR2 memory as the memory controller is inside of a CPU and so far we are not aware of any plans to release Bloomfield Core i7 CPU that would support DDR2.
