It depends on the use of the computer and budget. The X6 1090T is a good CPU but Intel's new Sandy Bridge CPU's are more powerful. We are still waiting for the SB LGA1155 Intel motherboards to come back in retail after their recall.

IMO i think you should wait until around April.Sometime around then the new Bulldozer CPU's from AMD should be released.When that happens you have the choice of getting a new Bulldozer or i'm sure the prices will drop for the old generation of Phenom ii's.And maybe if the new Bulldozer chips can compete with the Sandy Bridge it is also possible that the prices will drop for the Sandy Bridge.
I would suggest waiting but if you can't definitly pick up one of the new Sandy Bridge cpu's.They have the best performance compared to any prossescors on the market.
ah i see, still seems ridiculous. an extra $1250 just for 2 more cores and some new architecture. woop-de doo
Westmere is an older architecture.... Sandy Bridge is new...
Westmere has 6 physical cores and the ability to handle 12 threads "simultaneously"
Sandy Bridge Core i5 processors have 4 physical cores and can only handle 4 threads "simultaneously"
Sandy Bridge Core i7 processors have 4 physical cores and the ability to handle 8 threads "simultaneously"
But why would you buy the westmere i7 for $1500 when you can get the Phenom II X6 for around 250? I dont see how Intel makes money from everybody whos not a fanboy..
The ability of the Westmere 980 to handle 12 threads "simultaneously" compared to the PhenomII X6 only being able to handle 6 is enough for some....the better performance is enough for others. Core efficiency is also a factor....
