Would that be the SAPPHIRE 100352-4L Radeon HD 7950 3GB GDDR5 (black and red with single turbo style fan) or the SAPPHIRE 100352-3L Radeon HD 7950 3GB 384-bit GDDR5 (all black with dual fans)?

The reason I ask is because I have a rig with the 100352-4L's, and one of my cards burned out. I would like to replace it with the exact same thing, as I really like the way these things hash! I'm getting 700 KH/s right now, and would like to just be able to toss in a new one and go without changing anything. Are the used ones the same card as the new ones?

Thanks!!
