Finding the best graphics cards under £300 has never been more interesting, or more confusing. The GPU market in 2026 spans ancient silicon from a decade ago right through to brand-new RDNA 4 and Blackwell-architecture cards, all sitting within the same budget. Some of these deals are genuinely brilliant. Others are a waste of money dressed up in a shiny box. We've pulled together seven cards across the full price range, from under £90 to just touching £300, to give you an honest picture of where the value actually sits. Whether you're building a compact PC, upgrading an ageing system, or just want the most frames per pound, this guide has you covered.
Buying Guide: What to Look For in the Best Graphics Cards Under £300
Shopping for a GPU in this price bracket is genuinely tricky because the range is so wide. A £90 card and a £300 card are both technically in the same roundup, but they're worlds apart in what they can do. Here's what actually matters.
VRAM: 8GB is the sensible minimum in 2026. Six gigabytes will get you through most 1080p gaming today, but newer titles are already pushing past that at higher settings. If you're spending more than £150, aim for 8GB. The RX 9060 XT's 16GB is exceptional and future-proofs you properly.
Architecture matters more than clock speeds. A high clock speed on a ten-year-old architecture (hello, GTX 970) will still lose to a lower-clocked modern card. RDNA 4 and Blackwell are the current generations. Ampere (RTX 3000 series) is one generation back but still well-supported. Anything older than that is legacy territory.
Upscaling technology is a real differentiator. DLSS 4 on NVIDIA cards and FSR 4 on AMD cards can dramatically boost frame rates in supported titles. If you're buying a card without upscaling support (GTX 970, GTX 1660 Super, RX 580), you're leaving a meaningful performance tool on the table.
Memory bus width and type. A wider bus (256-bit) moves more data per clock cycle. But fast memory on a narrow bus can compensate. GDDR7 on a 128-bit bus (RTX 5060 LP) outperforms GDDR5 on a 256-bit bus (GTX 970) in practice. Don't fixate on bus width alone.
Form factor. Low-profile cards fit in more cases but typically have smaller coolers and can run warmer. Full-size cards have better thermal headroom. If you're building in a standard ATX case, a full-size card is usually the better thermal choice.
Brand and warranty. ASUS, MSI, Gigabyte, and Sapphire are established names with proper UK warranty support. Lesser-known brands like 51RISC carry more risk. At this budget, warranty matters. A GPU failure without proper support is a painful experience.
Power requirements. Check your PSU before buying. The RX 9060 XT and RTX 5060 are efficient modern cards, but older high-performance cards can draw more power than their specs suggest. A 450W to 550W PSU covers most cards in this roundup comfortably.
