Those look like artifacts you get from overclocking or could be that the GPU is faulty. You could try to run some GPU benchmark or stress test to see if you can reproduce it there.
Looks like an issue with the graphics card to me... try reseating, and as stonec said reset it back to factory clocks if you overclocked it and run a benchmarking tool to check it.
