Oddly this sounds like a bandwidth problem to me, with lower resolution (bandwidth) video you can use higher bandwidth audio. HDMI does have bandwidth limitations, I assume you are using 60 Hz; maybe test the theory with 30 Hz? It could be the cable, the receiver (I doubt it), or the video card (drivers or hardware) as both your cards a fairly similar. Do you have another receiver or something to test that end? How about another cable as unlikely at it seems?

Have you tried custom super minimal timings? Start with CVT Reduced Blank but set the front porch and sync width lower (maybe 2, 2 for Vertical?), you can also try lowering total pixels but not too much. Most devices don't break if you give them bad timings, they just do not display an image.
