I was wondering if it is worth getting a second 650 or sticking with a single GPU. I am not 100% sure that this system can support SLI as it is though. I over clock the CPU to about 4.3GHz. The max wattage seems to be at about 550 but the regular operating wattage looks to be around 480. with the SLI setup. I would imagine that the GPUs would not peak very much because my display caps at 60 fps. I would love your input.
