Hi and thanks for the help,
I have not overclocked the GPU or CPU.
(BTW you can see the artifacts in this dialog as well)
I get artifacts now as well when GPU is running at just 37 degrees.
Is there something I could test to determine if it is a problem with the GPU or the motherboard, before I try to replace the GX-card?
