Heat is a killer on my card at least. On the first 3D '06 run I hit 83c. I pulled off the HSF and applied AS5, got down to 75c on the second run. I almost burnt my finger on the heatsink though. I guess those NVIDIA engineers who have been saying "We're good to 100c" are pushing it a bit here.

Needless to say, the card was very stable at 700mhz core, and ran through a '06 pass as high as 733. I couldn't get much more out of it without doing better cooling and maybe this volt-mod. We'll just have to see how the cores do with about 1.2v.
