I am thinking of making a 2D/3D rocket ship of a PC. I am considering buying both the TNT based Viper 550 and the Voodo2 Based Monster 3D II and linking them together in one machine to get the best overall 2D/3D support. The CPU is going to be either a AMD K6-350/380 or Intel P2-350. Has anyone done this? and what is the performance like?, are there any problems?
