I would first start off by checking the other resolutions your monitor "likes" to see if the problem exists within this one resolution. If not, then I would have to suggest an RMA because it sounds like you got a bad chip.
Download Hardware monitor and watch your gpu temperature. min and max. Do the dots happen after 3d gaming /yes and or both ? Have you overclocked your card at all in ATI CCC ? http://www.cpuid.com/hwmonitor.php

I downloaded hardware monitor and my min is 23*c and max 30*c. I have literally had this pc for about 4 hours as it was built yesterday so no overclocking or anything. I have not even installed any programs or games just as soon as i turn it on this problem occures.
