Sapphire HD 7850 Video Card issue

Hi All,
I'm a noob to Tom's, 1st time posting yet I've read plenty on these forums, please go easy.

I have an issue with my newly purchased & just assembled PC.
When ever I play you tube videos I get "feedback" or "distortion" across my screen.

The issue occurs whenever I play any YouTube videos (in either Chrome or IE 9) using the HDMI or the Mini-DP ports,
yet the issue does not occur if I utilize the onboard Intel HDMI port.

As this video card is new to market, does anyone have any ideas how to get around the issue?

See for a small video of the issue, it happens a few times, esp @ the 0:16sec mark.

Appreciate any assistance from all the gurus here.

My system details are:
O/s: MS Windows 7 64-bit SP1
CPU: Intel Core i5 2500K @ 3.30GHz running at 37 °C
RAM: 8.00 GB Dual-Channel DDR3 @ 802MHz (11-11-11-28)
M/board: Gigabyte Z68XP-UD3 (Socket 1155) running at 40 °C
Graphics Card: AMD Radeon HD 7850 Driver version; 8.950.0.0 (The most recent I believe)
Graphics on-board: Intel(R) HD Graphics 3000
Monitor: S27A750D (1920x1080@120Hz)

Have you tried using a DVI cable? iirc HDMI and DP can't do more than 60hz, I honestly don't know if that affects anything, but if the DVI also doesn't work, we can probably determine it's the card or the drivers.

Unfortunately the Samsung S27A750D does not have DVI input.
Is DP1.2 is 120Hz capable? As the card supports DP1.2.
Yet the issue still occurs if I use the HDMI output from the Video card (then the refresh rate does drop to 60Hz).

Someone has indicated drivers:

As the card is only new I wondered that too.
Yet I loaded the one that came with the card: Catalyst Version 12.3 ... Same issue.
Upgraded to current latest version 12.4 ... same issue
Re-installed windows & loaded Win 7 certifed version 12.2 ... same issue.

Do you think Sapphire just havent perfected their driver for this new to market card?

Yet I see other people can run 3D Mark on this card, at times (not all the time) this even failed with my card?????

I have returned it to Point of sale (UMART Austrlia), and am still waiting.
Sapphire support have told me to do the same for "hardware checking and DOA or RMA".

I had the card replaced,
Turns our it was a hardware issue, new card works great!
