Well it looks that way, if you look at the release notes for 13.1 which you tried to install the 7470 is not supported.
I had an A8-5500 which I upgraded to a A10-5800K which has the HD 7660D which is supported by 13.4. The next release which is due out at the end of the month it may not be.
I currently have my onboard graphics disable because I'm using a discrete HD 7850 card with 13.6 beta 2. I had a need for more graphic power than the onboard could supply.
So does your system work? The reason for most people to upgrade is that they are having a problem and release there are upgrading to has the fix.
If there is to be an update for your 7470 onboard it will probally come via ASUS.
