Best PCIe Card: Entry-level

Best Graphics Cards For The Money: August 2012

Best PCI Express (PCIe) Card For £55:

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 still sad that the Radeon HD 5670 was discontinued. 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 £55 recommendation.

Best PCIe Card For ~£85:

Radeon HD 7750

Good 1920x1200 performance in most games, some with lowered detail

Radeon HD 7750
Codename: Cape Verde
Process: 28 nm
Universal Shaders: 512
Texture Units: 32
ROPs: 16
Memory Bus: 128-bit
Core Speed MHz: 800
Memory Speed MHz: 1125 (4500 effective)
DirectX/Shader Model: DX 11.1/SM 5.0
Max TDP:55 W

The Radeon HD 7750 is the fastest graphics card you can get right now that doesn't require an auxiliary power input; it draws all that it needs from a 16-lane PCIe slot. If you're upgrading an older machine with limited power supply capacity, that's an attractive point to consider. 

And it's a decent performer, too, particularly in light of AMD's most recent beta Catalyst driver package.
