Has anyone considered these machines for multi-GPU applications?
http://www.thinkmate.com/systems/supermicro/gpu [4] I would configure them here and then purchase from superbiiz.com or wherever your best pricing is. I have their servers running for my infrastructure and am quite happy otherwise (USA pricing).
