I have a gtx 780 ti windforce, and started noticing, that games started crashing more frequently due to directx, and wierd things i think they are called artifacts, like something starts changing colors, or flashing that shouldnt, as well as I had this wierd thing happen i have three monitors and turned 2 off to take a screen shot that wasnet extra wide, and the monitor started looking like a old movie with lines running down, it is not overclocked, well except for the factory oc that gigabyte did, should I call gigabyte and try to warranty it back? Or is this something else? Thank you for answering.
