AFAIK you need a radeon HD card -- so, no, CANDI won't work on your SAM. :(

yes, you can use off-the-shelf SI-based radeon HD cards with a PCI-to-PCIe adapter -- but if you do that, you'll lose overlay for your video playback. the newer GPUs out there don't have support for overlay. to compensate there is compositing video in version 2.10 of the drivers, and it helps, but if you like playing videos on your SAM, i'd recommend leaving the 9250 in there.

that said, as more and more games support compositing graphics, then it might make more sense. check out this youtube video for what i mean.

certainly you can do as you like, but as a former SAM owner, i'd stick with the 9250 and forego CANDI. the CPU in our 440-based SAMs are a huge bottleneck, so whatever you do, remember it's not comparable with the newer machines. the 'low CPU' option in CANDI was really designed for the 460, not for the 440. ;)

yes, the 128-bit memory bus is important for reasonable performance, but, again, the main contributor to poor video playback with some files is the CPU itself. that said, a 128-bit card will help. if you can't find one on ebay, let me know -- i think i have a spare 9250 somewhere.

as for overlay, it should 'just work' without any setup on your part. there is a NOOVERLAY tooltype for dvplayer that you can enable, but unless you did so, it's on. it's a shame i'm up in CT, or i could diagnose all this in person. can you tell me the file container and codecs used (video and audio) of the file that is stuttering? maybe can i help you cook up the right settings to play it well on mplayer.

no idea, tbh. i always verified the product number against something posted at newegg to verify, but yours doesn't come up. i would say that i've never heard of a 9250 that 256MB of VRAM and was 64-bit. the only 64-bit cards i've ever encountered were 64MB 9200-series cards or 128MB 9250s. i do have a spare 128-bit card at the house, so if you need it, it's yours. i can send it when i get back from holiday.
