How to buy a computer (part 1)

But if your requirements are greater, you want to edit media files, images, you need databases, you want to play the newest games… you have to think on a last generation computer. Even if technology progresses in a rapid pace, the acquisition of a top computer can help you save money in the future because it will face (up to a time) future software demands. Maybe one of the most active segments market sales of computers is a PC-gaming segment, for computer games. Crazy users spend hundreds of dollars for last generation graphical card and processors not just Dual-Core but Quad-core to get maximum performance. Do not be fooled, to play a game is not just a hobby, a passion for those who give you the money. Games industry worth billions annual.

But enough for now… let’s talk about the computer components and see what you have to know when you want to buy a computer:

Processor

Like I said, using a computer for applications like internet, emails and documents do not require a performing computer. But if you want more, then the processor can do what you want.

At this point processor market battle goes between Intel and AMD, two American companies. In many tests Intel Core 2 Duo have proved better than AMD rivals as AMD Athlon 64 X2. Do not consider however that AMD processors are weak. It’s just a situation of moment; not only once AMD was ahead of Intel. Anyways, in this case, Intel is in front of AMD, even both processors are dual-core (dual core - two independent processors connected in one circuit on the same silicon plate) so that processors that enable fast multitasking function through (several operations performed at the same time) with good performance for gaming and multimedia.

In case you still want a dual-core processor but do not have enough money for one of the top, you can find dual-core processors at lower prices but usually it falls in performance. Refurbished or used computers could be good options for a low budget.

It you are a game passionate, remember that even if a quad-core processor sounds great, one dual-core is definitely enough for most users. At this moment there are few applications that need quad-core processors and surely you will not use its full capacity.

If you are interested to find out more, Intel and AMD have detailed comparisons between their processors:

Memory

Computer memory (an electronic component that retain information and instructions so the processor can access them quickly) is measured in capacity. If more memory is installed in your computer, the applications will run easily and the system will work better. Memory is an essential component of the computer, without it it will not work, reason for which come preinstalled. However, anytime can be added a new memory module that will increase the capacity and the operations speed.

Motherboard

A motherboard should be bought thinking at the future and of course, depending on the facilities that it offers. The second generation SATA connectors (which reached a transfer rate of 3 Gb / sec), high-definition sound on board, and even dual graphics card (SLI or CrossFire) can help a lot in present as well in the future.

A very appreciated motherboard is Intel "Skulltrail". Its configuration is: Dual-socket LGA 771 for procesors which support Penryn chips on 45nm technology and also supports four x16 PCI Express 1.1 slots, two PCI 2.3 slots, six SATA 3.0 ports and two eSATA ports.

BUT before buying a motherboard, consider all the components you would like to buy them, choose the desired configuration and then go shopping

Computer case

A good computer case could make your day better when you want to do an upgrade. It should let you add almost any type of new component, it should be easy to open and let you move the components and everything should be proper ventilated.

If you plan to keep your computer a longer period of time, leave room in computer case for future components. Let free slots for memory, one for another sound card etc..

The most common cases are ATX format. ATX specification not only indicate where you should connect the plugs on the back of the case but also show you what source to use.

You can find different shapes and formats as MicroATX, NLX, BTX (new format seems to replace ATX, supported primarily by Intel).

Video card (graphics card)

Video card is responsible for generating all images on the monitor and can be preinstalled on the motherboard or bought separately. Their main characteristics is power. The integrated graphics card typically use the system memory to operate, while the dedicated video cards use their own dedicated memory. For the vast majority of users, integrated boards are sufficiently advanced, however, if you want to run games, graphics and other multimedia programs, a dedicated video card is recommended.

If you already have a computer, before you go shopping, find out what type of card fits your system. Or, if you get a computer try to find a system that have PCI Express x16 slot for graphics card. Although there are still motherboards using the AGP and PCI slots, they are already the past.

Hardisk

The hard disk size has increased enormously in the last 12 months, the current size reaching from 160 Gb till 1 terabite (1000 Gb). If planning to store large amounts of data, then the higher, the better.

Today’s most hard disks are Serial ATA and  they do have 7200 rpm; gamers will certainly appreciate the Raptor X 150GB hard disk at 10,000 rpm from Western Digital.

Monitor

It does not matter what it looks like, but what it does. Some things you should keep in  mind when you buy a monitor: optimal resolution (at least 1024x768). For higher resolutions, you need a better video card. Remember this when you want to get a 30 inch monitor. Remember the distance to the monitor. It is not the old problem of cathodic tubes but that you must include the entire screen with his eyes when working at the computer, otherwise you eyes will get tired very soon (and health problems could also appear).

Most people use 17 "or 19" monitors. Another option would be a 22" monitor, especially because the price difference is relatively small compared to the 19"s.
