Is My Brand New XFX Radeon 7970 Faulty?

" alt="" class="imgLz frmImg" />" alt="" class="imgLz frmImg" />on the 9th of December, 2012 3 days ago i purchased a XFX Radeon 7970 xXx Double Dissipation Black Edition from centrecom for $409 dollars. The first day i used it, it was fine but then the second day i was playing Gmod then randomly i got artifacting, but just glitchy textures my whole screen went all Distorted and stretched, my second screen was still working fine but my first one was all artifaced or however you call it, then the next day i got loads of artifacting again, 2 times while watching youtube and two more times playing assasins creed III but when i was playing it was just all pixleated and artifacting but not distorted and stretched still able to move my character fine etc, once that happened i closed it immediately, i then played left 4 dead 2 then a few seconds later i opened a youtube video on my second screen then boom stretched and distorted again! By the way i have not overclocked it more than the factory set one, haven't modified anything whatsoever just pretty much using it straight from the box and my temps are not going over 65degrees so im 100% sure its not due to overheating I',m thinking about returning it to Centrecom today (later since its 1am) but i want to see some reply's from you guys first! Greatly appreciated if you did  
BTW my specs are
AMD Phenom II x4 970BE stock 3.5GHz
AMD/ATI Radeon 7970 as of current ^ used to be A 6970(worked fine for 1 ½ years no artifacting/problems only 85+degrees gaming also still works)
750w PSU
8gb Ram DDR3 Corsair
WD caviar black 1tb /w OS windows 7 prof
WD caviar green /storage

Oh, and if i do in fact return it and they can possibly give me store credit i might just go buy a GHz edition one http://www.centrecom.com.au/catalog/r797to-gigabyte-797...
