And now for a really dumb question....

^^^ Yeah.

Source engine games support bloom on DX8 cards and other engines can probably also support it if the developer chooses.

It supports both bloom and HDR. It will allow me to turn on HDR with a reasonable performance hit but it does turn on. I always figured HDR was a SM3.0 feature..

Depends on your definition of HDR. For the full precision version, SM 3.0 is required.

But the HDR methods employed by Valve in HL 2: Lost Cost and their new HL 2: Episode One look fantastic.

Of course, I've SM 3.0 hardware so it's hard to tell what the difference would be for me.
