HEXUS.net has managed to take some pictures of two XFX GeForce 6800 Ultra 512MB cards running in SLI. These are reported not to launch until tomorrow, so this is a first look at them in action. The system itself (which has until now had its case panels securely in place) is being showcased at XFX's stand at CeBIT in Hannover, Germany. These cards bring an unprecedented 1GB of video memory to gamers.
