Intel Pentium 820 D 2.8GHz 90nm Dual Core

It wasn't too long ago that we were all asking the question, "Should I go dual core?" Times have proven that dual core is the future and has clear benefits, which turned that question into, "Which dual core should I get?" Even if you are buying the lowest dual core on the scale, you are essentially getting twice the computing power than from a single chip. As more and more applications take advantage of dual cores, it makes the buying decision easier. Of course, the ability to multi-task without slowing your OS down is another huge benefit.
Intel and AMD both have a great selection of dual core chips, for all wallet sizes. Intel dual cores almost always cost less than AMD's, which makes them look more attractive. Generally speaking though, tests have proven AMD dual cores better for gaming on high-end systems. But, if you are looking for a cheap solution to get yourself a dual core rig built, then Intels offerings are worth looking at.
Today's processor in question is the 820 D. It was the bottom of the barrel when it came to Intel DC's, until the lower clocked 805 D came out. But before we get into specifics and feature comparisons, let's delve a bit deeper into why dual cores are beneficial to you.
Features
PCs that have two CPU cores are not necessarily new, although it is for the consumer market. A few years ago, you would need two separate CPU's in the same machine. You can now have the same benefit but with only one CPU. There was a lot of speculation when dual cores came to be, but there's no denying just how beneficial they can be. Because you essentially have two CPU cores under the same IHS, multitasking proves less groggy with larger applications. As you open new instances of applications, the CPU will decide which core to use. The goal is to allow you to do more on your PC than with a single core, without having a sluggish experience.
Even though you have a dual core, things can still slow down your PC, but that primarily only happens with multiple intensive applications that are stressing the same components at once, such as ram or your hard drive. As a great example though, you could play a game and convert a video file at the same time and feel virtually no lag or slowdown. Try doing that on a single core and it will not be a fun experience. Because of these possibilities, it's no wonder why dual cores are growing in popularity.
