I'm looking for a PSU for a new computer. I want to get a Radeon X1900XTX video card. The system will be primarily for gaming, and I want to leave room for upgrading with a second CrossFire card if/when the time comes. I've read that you should have 550W with 38A on the 12V rail for CrossFire. What is the difference between single and dual 12V rails, and if I get a 550W PSU with a dual 12V rail and 19A on each rail will that suffice? The exact PSU I'm looking at is the Antec TPII-550.
