This chapter details the essential components required for building a computer. The process of consideration may differ from other guides, with an emphasis placed on parts crucial for gamers, and the remaining system built around those core elements.

2.1 Video Card

The video card, also known as a graphics acceleration card, display adapter, or graphics card, is technically considered a peripheral component. However, it remains one of the most vital parts for a gaming computer.

A graphics card is an expansion card featuring a GPU (graphical processing unit) chipset, dedicated to rendering graphics. Its primary function is to render and output (3D) images to a monitor. While most motherboards include integrated GPU chips, they are generally insufficient for gaming. An external, upgradeable component is therefore preferable.

This is a key reason to avoid gaming laptops. When the integrated GPU becomes outdated, replacing it necessitates purchasing an entirely new system, with limited reusability of existing parts.

Several factors must be considered when selecting the appropriate graphics card:

• What level of performance is required?

• What additional features are desired?

While prioritizing maximum performance is tempting, budgetary constraints often necessitate balancing functionality against cost, focusing on needs rather than wants.

Specific card recommendations will not be provided, as such information is transient. Instead, the focus will be on teaching you how to identify suitable options independently.

2.2 GPU Manufacturers

Currently, the two primary manufacturers of GPU chipsets are NVIDIA and ATI (the graphics division of AMD). Determining which is superior is subjective, with NVIDIA being the more commonly preferred choice.

Graphics cards from other brands are often available, utilizing ATI or NVIDIA chipsets.

2.3 How Powerful a Card?

When planning your purchase, consider not only current performance but also the card’s capabilities in the near future.

A high-mid range card is often the most sensible choice. High-end cards frequently carry a significant price premium for a marginal performance increase, which diminishes over time as gaming technology advances. A high-end card is only justified by a dedicated gaming enthusiast with ample financial resources.

Conversely, low-range or low-mid range cards quickly become obsolete. The gaming industry evolves rapidly, and these cards will soon struggle to meet the demands of newer titles. Accept that even good cards will eventually become outdated or decrease in value.

2.4 How do I know which cards are powerful?

Understanding this dynamic is crucial for evaluating graphics cards effectively. Unlike many other components, graphics card performance cannot be judged on a single metric; numerous factors contribute to overall capability.

Specifications alone can be misleading. Three key aspects can be gleaned from the product packaging:

Series – Cards are typically released in series (e.g., the NVIDIA GeForce 9600 and NVIDIA GeForce 9800 both belong to the 9000 series). The series is an important indicator; a newer series card is often superior to a more powerful card from an older series.

Memory – All cards have dedicated graphics memory. Larger memory capacity generally equates to better performance.

Suffixes – Understanding common suffixes is also important. In NVIDIA’s case, GTX denotes the highest-performing cards, followed by GTS, and GT for the lower end. ATI cards utilize similar suffixes, along with additional designations.

To ultimately select a graphics card, this knowledge will be used in conjunction with benchmark data.

2.5 What Benchmarks Are

Benchmarks are data sets that demonstrate a card’s performance during intensive graphical testing, such as frame rates during specific game sequences at various screen resolutions. These results allow for direct performance comparisons.

Tom’s Hardware is a valuable resource for benchmark data [No Longer Available], offering comprehensive charts and comparison tools.

Note that these charts may not include every recent graphics card. Google can be used to find information on missing models.

2.6 Thinking ahead

To remain competitive, it’s essential to account for recent developments and adopt new technologies promptly. Sticking with outdated technology is a surefire way to fall behind.

The following aspects should be considered when purchasing a CPU:

A high-mid range or high-end CPU is recommended for longevity, lasting at least 3-4 years. A decent CPU can often be found for around $100.

Your CPU choice will dictate the compatible motherboard socket. This limits your future motherboard options. Record the CPU socket on the component reference chart.

Clock (Cycle) Speed

Clock speed, measured in Gigahertz, indicates the CPU’s processing speed. It represents the amount of data the CPU can handle. A low clock speed will limit overall system performance.

Clock speed is a useful metric for comparing processors within the same series. However, cache and bus speed also play a significant role, so overall performance may vary.

Research current game requirements to ensure your chosen clock speed is sufficient. At the time of writing, a clock speed of 2GHz or higher is recommended.

Cache

While important, the cache doesn’t require extensive research. A higher cache size generally indicates a better processor, but it’s not the sole determining factor.

Frequently accessed data is stored in the cache to reduce access times. The cache is divided into levels (L1, L2, and occasionally L3), with L1 being the fastest and smallest, and L3 being the slowest and largest.

A larger cache stores more data, but also increases access time.

Multiple Cores

Multi-core CPUs are becoming increasingly common. These CPUs contain multiple processing units, allowing for faster communication between components. It’s like having multiple workers at a desk instead of one overworked individual.

The number of cores is increasing, from dual-core to quad-core and beyond. A dual-core CPU is a sensible and economical choice for casual gamers. However, quad-core CPU prices have decreased, making them a viable option. If affordable, a quad-core CPU is recommended.

HINT In the Intel lineup, ‘Core 2’ refers to the CPU series. Look for Core 2 Duo for dual-core and Core 2 Quad for quad-core. The latest Core i7 series features a minimum of four cores.

Boxed versus Non-boxed CPU’s

Boxed CPUs are retail versions and are generally recommended. Unlike non-boxed processors, boxed CPUs include a heatsink and/or fan, which are often not included with non-boxed versions. This avoids additional costs and potential compatibility issues.

USB and FireWire are used to connect external devices. FireWire is less common, but a sufficient number of USB ports is essential.

2.10 RAM

RAM, or Random-access memory, is the computer’s temporary storage. It stores data that is frequently accessed, allowing for faster processing speeds than a hard drive.

RAM is faster than a hard drive but more expensive per Gigabyte and loses its data when the computer is turned off.

Sufficient RAM is crucial for smooth application and game performance. Insufficient RAM can cause lag and visual deficiencies.

How much RAM do I need?

With current RAM prices, it’s difficult to have too much. However, exceeding 4GB may require a 64-bit operating system. 64-bit systems are becoming more stable, but 32-bit systems remain more widely supported.

A 2-3GB of RAM is recommended. Most new motherboards have four RAM slots, allowing for future expansion.

DDR, DDR2 and DDR3

Three generations of SDRAM are currently available: DDR, DDR2, and DDR3. Each generation offers increased speed and reduced power consumption. DDR is obsolete, DDR2 is the current standard, and DDR3 is emerging.

DDR3 is currently too expensive for the marginal performance gains. DDR2 offers the best balance of price and performance.

Different RAM Modules

RAM modules are categorized by speed, such as DDR2-400, -533, -667, -800, and -1066. These numbers indicate the data transfer rate. Motherboards typically support only a limited range of speeds.

While higher speeds are generally better, mid-range and high-range options are sufficient for most users.
