Graphics cards are of the utmost importance in rigs intended for gaming or workstation PCs. For graphically intensive software and high-end games, a discrete card like those here is a must. AMD and NVIDIA dominate this market, and both firms offer a huge variety of cards across a broad spectrum of prices – cards for gamers start at just over £20 and can reach almost £1,000. Features and cooling solutions are just as diverse, but with any card you need to check that your case has room for it, your PSU has the right connections and that its display outputs meet your needs.
