I have a new question to ask. What I need to know is, is this a good idea? My newest computer has four PCI-E slots, the top two taken up by my NVidia GeForce GTX 560 Ti, and I want to have Geek Squad at Best Buy install a Creative Labs Sound Blaster X-Fi Titanium PCI-E card into the bottommost slot. Would the fan of the graphics card get sufficient space so that the card would not overheat? Would leaving the cover of the slot second from bottom help any?
