Basically what the article says is that 10.3 Gbps is only real if it the cable has been I depends toy tested and found to be so, but what companies do is sum the color channels to get the 10.3 rating.
Furthermore, deep color and true 1080x1920 only requires 2.97 Gbps. Any category 2 HDMI cable is capable of 3.4.
If you plan in doing 3D or 4K things might be different as those will require a bit more speed, but simply contacting BJC and asking them will answer that question.
