Best PCI Express (PCIe) Card For £45:
Radeon HD 5670
Exceptional 1680x1050 performance in most games, 1920x1200 in most games with lowered detail
| Radeon HD 5670 | |
|---|---|
| Codename: | RV830 |
| Process: | 40 nm |
| Universal Shaders: | 400 |
| Texture Units: | 20 |
| ROPs: | 8 |
| Memory Bus: | 128-bit |
| Core Speed MHz: | 775 |
| Memory Speed MHz: | 1000 (4000 effective) |
| DirectX/Shader Model: | DX 11/SM 5.0 |
| Max TDP: | 61 W |
The Radeon HD 5670 offers best-in-class performance and DirectX 11 compatibility, along with all of the other Radeon HD 5000-series features, such as multi-display support and high-def audio bitstreaming.
The problem is, this card becoming hard to find as it is being phased out to make way for the similarly priced DDR3-equipped Radeon HD 6670. While the newer model does have a slight advantage when it comes to raw GPU capability, the memory bandwidth is much lower. As a result, we'll recommend the Radeon HD 5670 as long as we can find it available.

Best PCIe Card For ~£65: None
Honourable Mention:
Radeon HD 6670 GDDR5
Exceptional 1680x1050 performance in most games, 1920x1200 in most games with lowered detail
| Radeon HD 6670 GDDR5 | |
|---|---|
| Codename: | Turks |
| Process: | 40 nm |
| Universal Shaders: | 480 |
| Texture Units: | 24 |
| ROPs: | 8 |
| Memory Bus: | 128-bit |
| Core Speed MHz: | 800 |
| Memory Speed MHz: | 1000 (4000 effective) |
| DirectX/Shader Model: | DX 11/SM 5.0 |
| Max TDP: | 66 W |
The Radeon HD 6670 isn't really much of an upgrade over the Radeon HD 5670, and it's definitely slower than the similarly-priced Radeon HD 6750. However, we're going to give it an honourable mention for being the fastest card (at least compared to reference versions from AMD and Nvidia) that doesn't require an auxiliary PCIe power cable. That is to say its power requirements are entirely satisfied by a second-generation PCI Express x16 slot.
