Looking good
One of the great things with this device is that it can save old cards that would have been thrown out. I have 2 x HD5850 + 1 x GTX285 that can't run without it and now I can bench them again!
Please give more pics of the soldering, might also a few pictures of how you put it together? How big soldering Iron do you needed ?
Vdrop? I can't see many condensators But nice job
