lets keep some things in mind: This is a preview, not a final review. There may be some features (USB3) that may show up at the final release. Also, we were not able to see what these chips can provide in supporting a graphics subsystem with 40 dedicated lanes of PCIe2. They also do not have a aftermarket cooler to see what OC options there are. And PCIe3 isn't going to come out until next year with IB chips, not sure where people got that confused. Besides, there are no GPUs coming out with PCIe3 support until mid next year anyways.
Aside from that this is exactly what we expected. From previous articles we know that faster RAM doesn't make a huge difference, so adding native 1600 support, and quad channel over duel channel wasn't going to do much with the exception of server and large database apps. They are basically SB chips with 6 cores, and support of server hardware like ECC memory. These are not gamer or consumer chips, these are for professionals who do big monster multitasking stuff, and get paid based on how fast those projects compile/complete (think pixar, and other large studios). For them it looks like this will be a huge 30% upgrade, which is more than enough justification to drop tens of thousands in new rendering equipment.
Only thing missing in the article are temps. There was a rumor that intel was having trouble keeping these chips within their thermal rating, and I was wondering if that was why it did not eek out ahead of the 2600k on some of the single thread apps when it should have. But I guess we will have to wait for a retail chip and board to get that information.
