Sven, I have previously tested the 5770 in x-fire, and found a huge gain in frame rates in Metro 2033 (literally double), but did not have time to test anything else apart from 3DMark. Unfortunately you won’t currently experience this in CloD, although you may some time in the future, but I would recommend a single card over a multiple setup anyway – it’s just less hassle and will always work. If your budget stretches to a 6950 I would say don’t hesitate, it will be hugely faster in CloD, and match 2x5770 in games that support x-fire without the configuration hassle.
