|One up front question one might ask is how much are you willing to spend? That may significantly limit your choices.|
First off, you ask about Intel. This is where you start - regardless of the article. You owe it to yourself do read up on each component you are considering.
Essentially, you have two choices AMD and Intel. What you get depends on what your goals are - and cost: Intel is going to cost more but may give you less depending on your intentions. For example, I chose the AMD Phenom II 720 2.8 BE which I have OCed to 3.3. on air. I chose this particular processor because it is an OCing dream and is cheaper than Quad Core which is generally not needed because very few apps/games utilize four cores today (unless you are into serious number crunching) That's MY rationale; you should look at AMD, Intel and then CPUs within each brand and decide which suits you and your wallet. The thing to do is Google and read tech review sites (there are several good sites that just do reviews) and see what you think. At the same time you will learn about the finite properties of each component.
One interesting note: in the article look at their $850 system. I have the AMD Phenom II 720 2.8 BE, and ASUS M3A79-T Deluxe (an excellent OC mobo), two 750GB WD 7200 SATA HDDs, one Seagate 320 GB 7200-10 HDD, two Lite-On DVD-RW dual layer ODDs (one lightscribe) one 52x IDE CD-RW ROM, two ATi Radeon HD 4830 gfx cards, a Zalman 750W modudlar PSU (OK with the 4830s) and the Antec 900 case, and an LG L227WTG LCD. I spent about two months researching the components and decided on each based on reviews, needs, mfr reputation, features. Note the use of Antec cases throughout. Antec makes a great gaming case for not a lot of money. The 900 is takes the standard ATX mobo but is bigger than most ATX cases and quite roomy for good air circulation and components.
If you are going to lay down mucho deniro for your system, you really owe it to yourself to research each part. If you want to know, post back and I will give you my rationale for each of the components I bought.
