I have to strategically place my PCI cards for my recording rig and the best place to put my video card was in either slot 4 or slot 5, which is the last two slots near the bottom of the case. I'm using a IXMicro video card but it just plain doesn't want to work in those last two slots. I've heard of others running their cards in those lower slots, but maybe since my 9600 is a 9600/200 with a Tsunami board it's giving me a different kind of effect.
