Graphics Card advice

Hello,

I’ve been searching around for a good graphics card best suitable for blender’s game engine and generally the 3D viewport. I’m looking for something with support for the GLSL shading feature and open GL (what doesn’t have that now days, except integrated cards).

I’d prefer something by nVidia unless anyone knows of something better, and something perhaps not by ATI (i’ve encountered lots of problems with ati). If you could suggest a good graphics card but at the same time one with a reasonable price, it would be greatly appreciated.

I use at home a GeForce GTX 460 (165€). For my purpose the card have enough power and is very silent (gigabyte GTX 460 two fans). DirectX: 11 • Shader Modell: 5.0
Slowest framerate that I ever get in YoFranky (Blender 2.49b) was 55Fps.
