    Nice Review Chris...

    Looking forward to the further information coming out this week on Ivy Bridge, as I was initially planning on buying Ivy Bridge, but now I might turn to Sandy Bridge-E

    Great review as always Chris! looks like I'm staying with my 2500k for a while!

    Great and long waited review - Thanks Chris!

    Temps as expected are high on the IB, but better than early ES which is very good.

    Those with their SB or SB-E (K/X) should be feeling good about now ;)

    Now, time to read the review. :D

    It gets higher temps at lower frequencies? What the hell did Intel break?

    I really wish they would introduce a gaming platform between their stupidly overpriced x79esque server platform and the integrated graphics chips they are pushing mainstream. 50% more transistors should be 30% or so more performance or a much smaller chip, but gamers get nothing out of Ivy Bridge.

    It makes sense Intel is making this its quickest ramp ever, as they see ARM on the horizon in today's changing market.
    They're using their process to get to places they'll need to get to in the future

    OK after reading most of the review and definitely studying the charts;
    I have a few things on my mind.

    1.) AMD - C'mon and get it together, you need to do better...2.) imagine if Intel made an i7-2660K or something like the i5-2550K they have now.
    3.) SB-E is not for gaming (too highly priced...) compared to i7 or i5 Sandy Bridge
    4.) Ivy Bridge runs hot.......
    5.) IB average 3.7% faster than i7 SB and only 16% over i5 SB = not worth it
    6.) AMD - C'mon and get it together, you need to do better...
    (moderator edit..)

    Good review.

    To me it shows 2 main things. 1) that Ivy didn't improve on Sandy Bridge as much as Intel was hoping it would, and 2) just how far behind AMD actually is...

    It's a shame that this chip is marginally faster than 2700k. I guess it's all AMD fault. there is simply no pressure on Intel. Otherwise they would already moved to 8, 6, and 4 cores processors. Especially now when they have 4 cores under 77W.

    Yea yea I know most apps won't use 8 cores, but that's only because there was no 8 cores processors in past, not the other way around
