Had a spare Blu Ray reader and just overhauled an old AMD 64 X2 4400+ with a dual head 6600GT, 128M I think.
Will this GPU have enough juice to run the Blu Ray?
Do things like COREAVC help this class of GPU?
This is not the prime desktop for BD, nor the HTPC either, so not a show stopper.
It 'could' become a BD ripper though.
I think 6600 is HD decode capable, try using the purevideo codecs and give it a shot.
Starting with the release of the GeForce 6600, PureVideo added hardware acceleration for VC-1 and H.264 video, though the level of acceleration is limited when benchmarked side by side with MPEG-2 video. VPE (and PureVideo) offloads the entire MPEG-2 pipeline (except the initial run length decoding, variable length decoding, and inverse transform), whereas first-generation PureVideo offered limited VC-1 assistance (motion-compensation).
