Just as fast as an i7 3770k but runs much cooler.
Pros: Price - The price on this CPU is just about right for what it can do and offer. CPU Frequency - Stock @ 3.6ghz, Over-Clocked @ 4.4ghz, Intel turbo boost plus OC brings this to a whopping 5.1ghz. Temperature (liquid Cooled) - idle @ 32c, load @ 52c. Features - Since this CPU does not come with integrated graphics chip, it instead comes built with a PCI-e, RAM and a QPI (replaces the FSB) controller built on the CPU. Having them built on the CPU reduces the bottleneck found on other chipsets like the Z77 platform. This results in faster, low latency performance for the other components.(the IB processors have a ram controller built onto them but it is not as good as SB-E) This is also the reason why the upcoming Ivy bridge-E processors will also work with an X79 motherboard and because X79 motherboard were designed with future releases in mind. When IB-E releases all you will need is a BIOS update and you will get a new CPU, better controllers for the motherboard, and you don't have to spend a dime getting a new motherboard like you will with Haswell. So this is more future proof than getting a processor for an LGA 1155 motherboard. Gaming - People say when gaming to go for a 3570K or a 3770K, which they are really good for gaming, but, everyone overlooks the single most important thing about gaming and that is minimum FPS. This means that the Core i7 3820 will keep up with the stuff on the screen a lot better than a Core i7 3770k will. The one thing that the E series CPU's have a big advantage over from a regular Core i7 is the Physics. Games love Physics. Especially if that game uses NVidia PhysX and you own an AMD card. This CPU has enough physics processing power that it can render things like destruction, ragdoll animation, and particle collision a lot better than an IB processor.
Cons: No CPU cooler included - Stock coolers were terrible anyways. No integrated Graphics - SB and IB have a distinct advantage over SB-E and that is they have an a GPU built on them that include technology like Quick Sync for even faster video encoding. Performance per Watt ratio is not as good as IB. Motherboards are more expensive but future proof.
