The brand of the PSU will probably help as well, post that. The quality of the PSU can make a big difference.

That PSU is plenty for that. Shouldn't be an issue unless it's failing, which I doubt.

How are your GPU temps?

This is a bug from the driver. You installed the 13.4 WHQL right? I'm getting with flickers sometimes when I'm gaming (especially lol), this happens to my hd7950 and hd6670.
It could be that firefox gives the same flickers.


The other drivers don't have this issue as much, but I use these drivers because they fix the frame latency for smooth gaming.

Like I said, this WHQL driver isn't fully bugfree, the next official driver will fix this normally.

Try the 13.1 driver, that's an official one. Or try the 13.5 beta (which doesn't yet include the frame latency fix)

And yes, your card isn't the problem, I got this driver issue from 13.4 on 2 different cards too

Also use this tool to remove old drivers:

Did you have an nvidia card before this one?

Also install all files including to the download (catalyst,...)

EDIT: I don't have any problems with running firefox browser. Update firefox to the latest version.
