TUVE el dilema y al final
di el salto al i7, desde mi opinión si tienes 1000 euros para placa, procesador, ram disco etc... , merecen la pena.
Como siempre la grafica te hace cuello de botella en juegos, pero para todo lo demas son unos mounstruos, sobre todo con aplicaciones adaptadas...
Respecto a la RAM, no os preocupeis por que por unos 70 te sacas un pauqete tri-channel de 1333 en coolmod, suelen tener pocos y en cuanto llegan vuelan (llegan a las 4 de la tarde y a las 9 se acaban) pero si andas pendiente los coges.
Un presupuesto un poc omás conservador que el mio es
placa (no compreis las intel) 250 + procesador (720) 280 + disipador (noctua) 50 + ram ( 3*1gb G-Skill 1333) 80 + grafica (GTX 260) 230 = 890
Segun comentan no bajaran de precio en mucho mucho tiempo, y el error de TLB era en etapas de diseño
Parece ser que era falsa la noticia
http://techreport.com/discussions.x/15979Do Core i7s have a Phenom-like TLB issue? No, says Intel
by Cyril Kowaliski — 4:11 PM on December 1, 2008
While browsing news sites today, we came upon several reports saying Core i7 processors suffer from a translation lookaside buffer-related erratum. Those reports drew parallels between the TLB bug that plagued AMD's first quad-core CPUs and a note in Intel's Core i7 specification update, which states in part:
In rare instances, improper TLB invalidation may result in unpredictable system behavior, such as system hangs or incorrect data. Developers of operating systems should take this documentation into account when designing TLB invalidation algorithms. For the processors affected, Intel has provided a recommended update to system and BIOS vendors to incorporate into their BIOS to resolve this issue.
We asked Intel PR manager Dan Snyder for the chipmaker's official take on the issue, and he replied with the following:
This is simply a pointer to a previous document written in April 2007. This document is an application note (advises on programming techniques) that programmers have had since April of 2007. This item in the Nehalem spec sheet is a web pointer, under the heading "spec clarification". The reporter who wrote this did not contact us and we will try to clarify this with him.
In other words, Intel shareholders probably shouldn't be losing any sleep over this.
For reference, the AMD TLB erratum caused data corruption and system hangs in periods of high CPU utilization, and AMD halted shipments of quad-core Opterons for months because of it. On the desktop, the company released a BIOS fix that crippled the performance of early quad-core Phenoms in many apps. All Phenoms with model numbers ending in "50" and all shipping quad-core Opterons lack the erratum, though.
Update: Snyder has sent us a new statement that makes the situation even clearer:
The "AAJ1 Clarification of TRANSLATION LOOKASIDE BUFFERS" document is a SPEC CLARIFICATION, and is simply a pointer to a previous document written in April 2007.
SPEC CLARIFICATION AAJ1 was initially added due to an issue on the Intel® Core 2 Duo processor which was previously corrected with a BIOS update; this issue does not impact the Nehalem Family of CPUs. There are errata on the Intel® Core i7 processor that relate to the TLB. These all relate to improper translations or error reporting, and all of those that impact functionality have been fixed via BIOS updates prior to Core i7 launch.
