What is the cool technology "thing" of the day. Well this has been around for a while, but now you have the ability to link two video cards together (called SLI) to get one big super card. Only problem, it's going to set you back a ton. Only the high end NVidia cards will do it, and they cost around $250 a pop for the lowest end SLI cards from Nvidia. You do the math...$500 plus the cost of the chip to connect the two.
People like my brother would have a hayday with this type of technology. Only for the true enthusiast. You can read more about SLI by clicking on the link below.
