To all the gamers out there that remember the Voodoo cards and the 3d rendering cards that required a 2d card as well for the general out put, look no further than the ATI Crossfire. From the review over on Anandtech my tongue is definitely hanging out of my mouth. The catch behind it all is that it requires that you have two PCI-Express slots, one for your video card and one for the Crossfire. For a picture of how this setup works - click here. Apparently a couple of motherboard manufacturers out there are beginning to make motherboards with two slots, but still, it’s pretty ridiculous if you ask me. I’d defintiely be interested in seeing a computer with this running though
