I'm getting the distinct feeling that the new Radeon HD 5770 I purchased is having some issues.
In any of the other games that I've tried it with so far (TF2, GTA4, HL2: EP2, etc) it's performed fine with no problems, however in WoW I have had 3 separate occasions where anomalies have appeared. Twice while flying, the most serious of them while standing in Dalaran.
While flying, I have twice now experienced an issue where the certain drawn portions of the screen would disappear completely, among them being the UI itself, the wings of my mount, and water effects. Below is a screenshot for reference:

The most serious though, and the one that's leading me towards wanting to RMA it, is while standing in Dalaran one night before a raid my entire screen turned ot nothing but beige vertical lines. After a hard reboot everything was fine again, however until then it was basically a complete system lockup.
Typically symptoms like this lead me to believe that there is something faulty with the video card, however I would also appreciate any input as to whether this could also be something software related.
