In order for that configuration to work, you’d need EVGA’s X58-based motherboard. The ASUS Rampage II Extreme, used for testing throughout this piece, will not support a three-way SLI setup, despite having three x16 slots. Bear in mind that 3-way SLI isn’t just about how many slots you have free—it’s all contingent on the platform you’re using. The cases with eight expansion slots, however, will work regardless, even if the third double-wide card hangs off the bottom of the board.
