So has Intel supplied us with another top-notch CPU ? Sadly it appears to be no :)
From what I can tell its Sandy Bridge but smaller :) Well in most benchmarks Ivy does appear to take the lead as you would expect but its not a out right victory, yes its great if you need that extra performance but if you need the horsepower id suggest something form Intel's 2011 CPUs
It also gives little room for overlooking with just a few volts anything over 4.7ghz and beyond your chip is going to get crispy fast so you will need a good cooler furthermore I see no reason to upgrade from SB to IB the PCI 3.0 appears to make no difference as games don't use that etra bandwidth
tbh i would stick to what you have now or upgrade to SB
The Good -
Superb quad-core performance
Outstanding Quick Sync transcoding
Class-leading power consumption
IGP can drive three displays
Improved graphics ( you can get 2 more frames on crysis now !!)
The Bad -
Not a huge step up from Sandy Bridge
Average overclocking potential on air
