What graphics card would you recommend for Cycles in Blender?

I may be getting a graphics card soon. I’m not rich or anything, so cheap, but effective is the key here. I can probably lay down about 80 dollars (before tax).

I need it to work with the Cycles renderer in GPU mode. My current card is a PNY nvidia GeForce 210 graphics card. Unfortunately, the CUDA is .1 under the bare minimum needed, and so is the CLSL. . .
