dynex 520?

Try reloading your drivers. Otherwise generally artifacting means that the card is dead, or overheating.

I thought it could also mean the card isn't receiving enough power?

It could be, but your current PSU is outputting more power than the old one. So unless you did not attach both power leads, then you are getting plenty of power.

Just opened up the case, everything looks in order. Reseated the video card, I seriously seriously seriously doubt its going to help though.

What if it is a defective unit, would it just not work at all?

been running Ati tool stress test for 30 minutes with no errors or temps over 75 celsius, strange.
