I've got my machine up and running and am about to install my Audigy 4 Pro. I had read in another thread where some folks were having issues with one PCI slot or another. I have an A8N-SLI with dual GPU cards. Also, I am going to install NV 5s which with take out the slot below the second card. That leaves the last two for the Audigy. For air flow and temp purposes I would like to have it in the bottom slot. However, at least one person has had problems with this. Just wanted to see where everybody was putting their cards. Also if you are running other cards, where are those located?
