Choosing Graphics Card?

I need a new graphics card and it must have at least---

3D graphics processor with Vertex and Pixel Shader capability with 128 MB VRAM - Such as an ATI Radeon X1600 or NVIDIA 7600 class card or better.

I have a max output of = 350 watts (18A) and a budget of around £70

Quad core PC with 6GB DDR2 (RaM), HD monitor

any recommendations appreciated, i really dont want to get the wrong card and have to mess around sending it back and find a new one. =)

I don't understand what's going on, but I would suggest you buy a 450 watts power supply first before investing in better hardware.

Also consider specific vertex and pixel shader models (1.1, 2.0, 3.0, 4.0, etc...) for e.g. DiRT and GRID won't run with less than Shader Model 3.0.
