Is it possible that one of my PSU's 6-pin power connectors is faulty and wasn't supplying enough juice to the 6770? Is that a thing that might make a video card work fine unless it was doing actual 3D gaming stuff? The PSU is a Antec 500W.
I can't say that it's specifically one connector being bad, but yes lack of power can do exactly what you described. I've seen systems doing that, swapped power supplies without changing anything else and system ran perfect.
Drivers, which you checked, are the next most likely problem. For some reason cursor artifacts, especially with dual monitors, seem to be common with Radeon cards. I hadn't seen any for around a year with my 7870, but the newest drivers (Oct 12th download) re-introduced them. This time at least the cursor only tends to flake out on the 2nd monitor and not the primary. Of course the slow loading and other display issues, while still potentially a driver issue aren't really the same things as the cursor issue.
The other most likely issue that I've seen with that is not heat on the GPU, but a memory issue on the video card.
