x800 series HDR?

do these cards support hdr?

Nope. That's one of the main advantages that Nvidia had over ATI in the X series versus the 6 series last year.

Go for geforce 6800 or 7600 or radeon 1800 series instead, x800s don't support hdr,but they support bloom

Yes but not the FP version. That means they work with HL2, Painkiller, Riddick (etc) but won't work with the likes of Oblivion, Far Cry and Serious Sam 2.

Yes, what IS FP? I don't even know. I was wondering why it worked with HL2

FP means rendering to a floating point framebuffer.

The X800 series doesn't support this but it does support alternate forms of HDR like the version used in HL2 for example.

X800 supports the HDR Standard established by Microsoft, it uses pixel shaders to render the HDR. I don't know how it works exactly, but I heard that it uses 16 Bits Integers to do the calculation and then its rendered to a Floating Point Texture and then to the pixel shader unit. The HDR used by the GeForce 6xxx, 7xxx and Radeon 1X00 is based on the Open EX standard that uses 16 Bits Floating Point Blending to create HDR. I heard that both methods works the same, but the later one tends to be a bit more realistic but the impact on performance is considerable. As a matter of fact the 1X00 series supports many different mathematical calculations for HDR like Integers in 12 and 16 bits, and Floating Point in 10, 12 and 16 bits and many other that I don't know.
