It doesn’t actually work, but if it did it would be formidable. Nick V put this thing together as part of Lego competition Iron Builder; he calls it the “PowerBuild CRLMRM IRON HD 1640 9IB 64-bit HNSL DVD Extreme x32 HD Ready ABS Support Video Card.”
Get ready for the latest development in plastic-based video card technology! The PowerBuild IRON HD Video Card features state of the art construction including a Carl Merriam endorsed 7-blade fan to deliver smooth techniques and visual displays whilst running at a constant cool temperature.
Apparently it runs 1640 stream processors, 9IB 64-bit ABS Drive and has third party enhancements—if you tune your imagination just right.
