Things you must see while buying a Desktop

Purchasing computer for home or business purpose is a tough call and it becomes tougher with the exceeding number of choices that are prefaced in the market every day. In order to pick the best one around, you need to have thorough understanding of what you need in your PC. Below is a list of computer components that you should check before buying a computer.


CPU is one of the most important components of your computer. The processor you choose for your computers will decide your PC’s shape, size and performance. In general, the higher is your CPU’s clock speed; the better is its performance and of course, the higher is its price. Another specification to check is the cache size. More cache size is always better. Core i3 and i5 processors offer 4MB cache whereas Core i7 processors give you 6 to 8MB cache.

If your PC’s requirement is limited to word processing, limited media playback, web surfing an Atom processor should work fine for you. However, if your PC has to handle high-end work or serious gaming, then you’ll need to have Core i5 or i7 processors.

Graphic Cards:

Graphics Processing Unit is responsible for whatever is displayed on your computer screen. Whether you watch videos or play games, a GPU is required to do it. Your computer has an integrated GPU, built on the motherboard or in CPU itself and if you are not interested in high-end games, then the in-built CPU will work perfect for you. However, if you have keen interest in high-end gaming, then need to have a discrete graphic card. NVidia and ATI offer a wide range of GPUs to choose from. If you are interested to buy one, you need to keep on simple thing in mind; the higher the number better will be the graphic card and higher will be its price tag. GPUs also depend on the size and brand of your motherboard. For gamers with generous wallet, its best to go for ATI’s Crossfire or NVidia’s SLI technology. A high-end graphic card will cost you in the range near about $150 to $350.


If your computer is for a little more than normal web surfing, emails and word processing, 2GB RAM is well to do. More RAM allows you to run multiple programs simultaneously and it helps improve your computer’s speed and performance. Today, all computers generally come with a minimum 4GB of RAM (though small budget PCs may have 2GB or 3GB).

If your computer needs to handle serious multi-tasking or heavy games, then you need to have at least 4GB RAM. If you do image or video editing, your computer might ask for more (8GB or 16GB). If you are shopping for RAM, you’ll notice two different types: DDR2 and DDR3. Among the two, DDR3 is faster and more expensive.

Hard Drive:

Even the most basic PC should have at least 320GB or hard disk space (though small PCs start with a size of 160GB). Power PCs offer 2TB or even more with options to combine solid-state drive with a hard drive. If your data storage requirement is high, 750GB or 1TB is a fair size.

Keyboard, Mouse and Removable Storage:

Though small but these are also very important components of your PC. Removable storage like CDs and DVDs are necessary and nowadays we have Blue-rays to offer amazing video quality. Wireless mouse and keyboards are good to choose if you get irritated with the tangles on your computer desk.

If you keep these things in mind before buying your PC and choose your computer wisely, you’ll never regret your choice.
