I'm not sure if this is a problem with my new Dell u2711, or my XFX 5870. I'm inclined to think it is not the display. The system is a new build -- I just built it on Monday -- and I got the display today. After switching to a dark wallpaper, I noticed green pixels randomly appearing and blinking on the screen. I've tried both a DP and a DVI cable, and it appears with both. One thing I've noticed is that just moving the mouse on the screen will change the speed that the pixels blink at. Some remain solid, but others blink, with varying speed. They appear to be stuck pixels, but when they go away the whole screen appears normal again. You can also see, in the second video, when I drag over the first pixel, another pops up as soon as it goes away.

There's a similar thread about that here: http://hardforum.com/showthread.php?t=1479054

I get them too. Just randomly. I got them as well when I had a GTX295, though much less frequently than with the 5870. It doesn't appear with *any* of my 2007FPs though. I think it's the monitor... but I've learned to live with it.
 
The display works fine on another computer, but another display, a 20" Dell, shows the same artifacts on the new computer. So, the problem is with the computer. It only seems to happen with grey colors. If I change to a black background, it never happens. But if I use a black background that has shades of grey in it, the green dots begin popping up in the shades of grey. I guess I'll just swap the video card and see if the problem goes away.
 
Occasionally I get them in mass quantities, happened with my 9800GTX, my GTX 275, and my ATI 5870 on an older LCD monitor of mine. It's rare though and usually only happens when browsing dark websites. I just brushed it off as my monitor failing. Hasn't happened on my newer ASUS monitors yet.
