Another option for the single PCI express slot is a Video Display Board with a DVI-I output. Further, the Cell in the BCU-100 offers the full 8 SPUs that Cell is manufactured with, as opposed to the 6 SPUs available in the PlayStation 3, which has one SPU disabled to improve manufacturing yields and one reserved for the system. This gives the BCU-100 an extra 33% potential CPU-power (or 51.2
