Welcome to the forums rocketman2!
It sounds to me like your GPU is either not getting enough power or has unstable memory.
Please post your full system specs including any overclocks, your PSUs manufacturer, wattage and +12v amperage.
Try using Rivatuner
to underclock your GPUs memory and see if you still have the artifacting problem.
Assuming your card started at stock clocks (ie, you have not overclocked it) and underclocking the memory fixes the issue, you should make an RMA request as you have a faulty card.
