Summary: I am thoroughly impressed with the ability of this CPU to overclock to 4.6ghz with no problem. (I use a Sabertooth x79 mobo and a Hyper 212 Evo air cooler and it stays under 45 degrees. Excellent product.
Summary: Quad Channel RAM will be the only way to go for this PC enthusiast from now on. You do not think of making your main rig less than a Quad Channel rig once you get used to it. With PCIe 3.0 your video game play is always a notch better. You will not falter playing the newest games on Hi-Res everything maxed out. In fact, i7 3820 is begging for more video card. I see low CPU usage in Task Manager, maybe 20-25%.
Summary: I purchased this for a combined gaming/simulation build. I've never had any trouble with it and it easily handles anything I throw at it. As part of my job, I run parallelized simulations so it runs at full load for extended periods and is perfectly fine. I've seen some people complaining that it doesn't come with a heat sink, but if you are buying a processor like this and plan on fully utilizing it, you don't want a stock cooler anyway.
