Platform Update KB2670838 performance issues

Hello all,
I see there was an old thread regarding this issue but I am having issues with performance every time I install this update, when I uninstall it the issue goes away. Curious if there is any more information regarding it like a fix or recommendations. From what I understand there is a conflict with certain northbridge chips, video cards, etc. I have a Amd 9370 cpu, asus 990fx rev. 2.o motherboard. To be more specific with the update installed I lose serious frame rates in games and the computer is just noticeably much slower in its response. I have updated all drivers and have the latest bios...at present I am just not installing the update. It would seem to me that this problem hasn't been addressed by Microsoft or the manufacturers. Any Ideas guys and gals?

I think I got the correct files attached here, not sure I ran sfc scannow and it said no errors....thanks for the reply let me know if these are the right files and if you need anything else :) thanks

oh it didn't send both here is the cab file

well it seems to not be sending the cab file its below 8mb and its in rar lol any suggestions? not unless it worked this time it was saying invalid file...
