I got the Corsair based on some great advice from the forum and after reading the Jonnyguru review. Installed w/o a hitch in my p180B. Just realized something I wish I would have known.. If I decide to go SLI, I am SOL right? I only count two PCI-E modular power slots in the power supply. SInce each card takes two power connectors, then SLI = 4 right?
