Hi there aqua. I would like to know what's the exact method you're using to change one card's bios from 9800GT to the FX3700 equivalent. Obviously changing the ID number(s) alone does not work (I've tried it). Do you also mess with timings, what about fan speeds (mine is stuck at 100% when I tried to use one of your bios). No matter what I tried I can't change *my* 9800GT's bios to FX3700 equivalents, only your bios work but since they are of different models they have many bugs in my system (recognize half the VRAM, full fan speed, only windows recognizes the card, etc, etc).
