iirc it crashes frequently and the performance benefit is just not worth it (2x the price and you only get like 130% performance or some shit)

Untrue. My SLi GTX 460 setup performed absolutely great. I got double the FPS in many games, it was only AAA titles that got the performance boost, but it was those that needed it. There were some games that didn't play nice with it but they were few and far between. It did have issues with micro stutter though.
