The processor is the brain of your PC, and the main component that will control the performance of your desktop. It’s important to make sure the processor socket matches the motherboard, so remember to check that they are compatible. For demanding programs, consider the most powerful processor you can – updating your processor at a later date can be awkward.
A dedicated graphics card is vital to gaming. The more powerful the card, the higher you can turn the graphics settings. More powerful graphics cards deliver smoother gameplay and are capable of displaying resolutions beyond 1080p. The graphics card is one of the easiest components to upgrade - just make sure you have enough free space inside your PC and an adequate power supply.
Power supplies deliver power from the mains to the components within your PC. Higher performance components may require you to upgrade your power supply to deliver enough power. Modular power supplies make it easy to keep your PC tidy as you only attach the cables you require.
Random access memory (RAM) allows your PC to effectively handle tasks – the more RAM your PC has, the more processes you can run at once. Demanding software such as Photoshop and Cubase will require large amounts of memory to perform. Installing new memory is simple – just check to make sure you add the same type you already have installed.
Internal hard drives
Many desktop PCs on Currys offer space to install additional hard drives, which are perfect for increasing your storage space or backing up documents in case another drive fails. Backing up means you’ll be able to boot your PC from a backup drive and minimise data loss.
Our range of PC cases are ideal if you’re building a PC from scratch. There are plenty of varieties to suit your needs, including compact and functional cases and high performance cases with integrated cooling that are perfect for gaming PCs.
PC fans and coolers
PC fans move air throughout your PC case and help to keep your PC cooler, while coolers can be used to distribute heat from individual components. It’s a good idea to upgrade your fans if you’re adding high performance components to your PC, or if you have a compact PC case with components close together.
Great for recording and creating music on your PC, a sound card lets you capture high quality audio without lag. They’re also ideal for gamers or media-fanatics as many allow you to attach sound systems to your PC to immerse yourself in entertainment.
PCI slots in your PC provide space for interface and expansions cards that let you increase the number of ports or add wireless connectivity. They’re easy to install and make expanding your PC straightforward.
