Affordable 2x HDMI/Displayport capture device?

Hey all,

I’m investigating different ways I might be able to record the output of 2 renderer windows in real time at high resolutions and framerates. A method with low performance overhead would be to use a capture card, but I need something that can handle 2 simultaneous inputs and runs externally either over usb or to internal storage. Any recommendations?
