Best PCI Express (PCIe) Card For ~£60:
Radeon HD 6670 DDR3
Good 1680x1050 performance in most games
| Radeon HD 6670 DDR3 | |
|---|---|
| Codename: | Turks |
| Process: | 40 nm |
| Universal Shaders: | 480 |
| Texture Units: | 24 |
| ROPs: | 8 |
| Memory Bus: | 128-bit |
| Core Speed MHz: | 800 |
| Memory Speed MHz: | 800 (1600 effective) |
| DirectX/Shader Model: | DX 11/SM 5.0 |
| Max TDP: | 66 W |
We're really sad to see the Radeon HD 5670 evaporating from retail. Although it's true that the Radeon HD 6670 DDR3 has a more capable GPU featuring a 25 MHz faster core clock, four more texture units, and 80 additional shader cores, the 5670 wields more than two times the memory bandwidth thanks to its 1 GHz GDDR5 subsystem.
Nevertheless, without any significant competition, the Radeon HD 6670 DDR3 assumes our $70 recommendation. Granted, if you're able to find a Radeon HD 5670 at this price, that's the route we'd truly suggest
Best PCIe Card For ~£75: None
Honourable Mention:
Radeon HD 6670 GDDR5
Exceptional 1680x1050 performance in most games, 1920x1200 in most games with lowered detail

As we've already established, 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 the GDDR5-equipped version of this board an honorable mention for being the fastest offering (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.
