Everyone of these cards is $110-$225 -- which one of (*These) cards would you recommend for the best bang-for-the-buck?
Also, which ones support High Dynamic Range Lighting (HDR), if any?
thanks for all your input

The X850 does not support Shader model 3.0, so does not support most versions of HDR.

The nVidia 6 & 7 Series (6600GT to 7800GTX) have Shader Model 3.0 and HDR, only the ATI Radeon x1000 Series (x1300 to x1900) have Shader Model 3.0 and HDR, x800 Series and below (x850 to x300) have no HDR or Shader Model 3.0. If you're choosing between 1 of those cards, get the x850XT, performs better than the other 3, I know this because I have all 4 cards, the x850XT is the best.
