Reviews Word on the street for the Intel Core i7 3770K

And because Ivy Bridge chips like the Core i7-3770K are intended for more middle-of-the-road users, they come loaded with integrated graphics systems that can drive up to three independent displays and support HDMI 1.4a and its associated high-quality audio, in addition to InTru 3D (for stereoscopic 3D) and HD video conferencing.

It's hard to imagine any desktop PC user ever needing more performance than the new Intel Core i7 3770K serves up.

Was just playing BF3 about 5 minutes ago, and the processor is now idling at 31-32C(according to PC Meter).

Moving past the LGA1156 Lynnfield processors, Intel launched the LGA1155 H2 socket along with their new 'Sandy Bridge' processors.
by Legit Reviews (May, 2012)
The Ivy Bridge technology in this processor is great, however I found that when OC'ing it was extremely sensitive, and by that I mean, with 0.01v added to Vcore, temps went up experientially (this was at 1.25v @ 4.2ghz).

Results: The Intel Core i7-3770K processor did great in the Sandra multi-media benchmark.
by Legit Reviews (Apr, 2012)
Benchmark Results: The GPU score for the Intel Core i7-3770K is the second highest for this test platform.

We were able to overclock the Core i7-3770K up to 4.8GHz with full stability.

If you're overclocking you will lose efficiency, but gain overall system performance.
by Legit Reviews (May, 2012)
If you aren't familiar with overclocking since the Intel 'Sandy Bridge' launch in January of 2011, it's been a trip.
