Make sure the fan on the card is spinning. The side door is not interlocked. No hazardous Voltages are accessible to your unaided fingers, but components may be HOT.
If it is, then try monitoring the temperature in that area with Temperature Monitor (free utility).Beige G3, G4/867, G4/dual 1.25 MDD, MacPro'09 w cheap SSD, Mac OS 8.6 or Earlier, and 9.2, 10.5 and Server - LW IIg, LW 4/600, ATalk ImageWriter L

Hmmm seems doubtful that it's heat because I can unplug the DVI cable and put it back in and goes away for hours. Sometimes when booting it is there right away. I will check the fan.

If you are confident it is not heat-related, the card may be failing.
These cards require 10.6.4 or later, but I think you said you had that, and this failure is not characteristic of mere driver problems.Beige G3, G4/867, G4/dual 1.25 MDD, MacPro'09 w cheap SSD, Mac OS 8.6 or Earlier, and 9.2, 10.5 and Server - LW IIg, LW 4/600, ATalk ImageWriter L

The problem with 5770 etc in a 2008, you can't buy 10.6.4+ on DVD to boot from, so do make sure to have some extra boot volumes.

I'm running 10.6.7 and perhaps it is a heat problem as I have my older geforce 8800 in the next pcie slot to run two other monitors. Can I move the 8800 over to the next slot to have a bigger gap between the two cards or is that not a good idea, not sure if it has the same bandwitdth rating. I will check the slot specs out later today here on the Apple site.
The fans seems to be working fine but the card is very hot to the touch and its been hot hear lately. So maybe it is heat realated.

I have a store bought Leopard install disc and Snow Leopard disc I believe I can boot off either one of those. I have a clone of my systme and two other bootable system drives as well.

The 5770 it self can run three monitors. Admittedly, with some very big asterisks attached.
If they are DVI monitors, you need ACTIVE, POWERED Mini DisplayPort adapters. If these displays are 1920 wide or less, there are some less expensive solutions that ATI approved.Beige G3, G4/867, G4/dual 1.25 MDD, MacPro'09 w cheap SSD, Mac OS 8.6 or Earlier, and 9.2, 10.5 and Server - LW IIg, LW 4/600, ATalk ImageWriter L

There is no support for the graphic card with older versions - that is one of the limitations of Apple's drivers, and lack thereof on DVDs.
Just as the 8800GT req'd 10.5.2. The 5770 requires 10.6.4 (10.6.5+ preferably, though later 2009/2010s can boot with 10.6.3 (one or two mentioned that) the 2010s had a special build of 10.6.4.
Windows, you don't have that limitation, there is basic video output w/o or in Safe mode.
Most of the requirements on product page (ie, 2009 or later, or PCIe 2.0) almost have to read between the lines or take with a grain of salt. Except minimal builds. Just as new Macs can't boot from older OS version.
You probably while trying to work through this out to try with just one graphic card or the other, and at least you have the 8800GT so you can boot from 10.6.0 or 10.6.3 DVDs. But you can't run or boot Leopard.
You might want to setup some clean Apple only emergency boot volumes - full updated - for maintenance purposes, and to build a solid OS that you can use to clone and build a full working OS.
One concern we had was the existence of the two Mini DisplayPorts in addition to one DVI port. We can confirm that the 2008 and 2009 were able to drive our 23" Cinema displays with the Mini DisplayPorts (using Apple's Mini DisplayPort to DVI adapter). I'm confident that the 24" LED Cinema display and soon-to-be-shipping 27" LED Cinema display will work fine as well. As for our 30" Cinema display, we used the DVI port while testing the 3G game listed above.3.2GHz 8GB DDR3 1600 GTX 460 / GTX 260, Windows 7, Mac Pro 8800GT Corsair F120/F90 10.6.7

My computer boots fine with both cards and I have a clone of it. It is really a minor issue and only happens every once in a while. Usually when I pull out the dvi connection and plug it back to the 5770 in the green pixels go away. The 8800 never had the problem by itself or when it is in the mac pro with the 5770 it's just 5770. I don't want to run thee monitors off the one card as I don't want to spend 200 dollars on mini port to hdmi adapters when I have a perfectly good video card that can run the two secondary monitors which also enables my 30 inch to have all the vram available to it instead of dividing it three ways among three monitors.
I really just wanted to see if anyone else out there has the same issue with the same setup.
2008 mac pro and ATI 5770. I could run just the 5770 as an experiment to see if it still does it without the other 8800 installed but it might take days for it to happen.
Thanks for the input you guys and I am keeping this open to see if anyone else has had the problem that actually has the 5770 and a 2008 mac pro.

Lance I have the exact same issue, you are not alone, as soon as my wallpaper changes with less blacks, the issue subsides. Temps are fine. BTW I use menu meters for a more complete analysis.

Hey Jazzimus, thanks its good to know its not just me. I have gone a few weeks without making any changes and the green pixels have not shown up lately. The tempuratures have not been as hot in my house so maybe it is heat related... but not sure. Is "menu meters" an app?

I've been having the same issue lately. I keep my Mac Pro temps at about 85 degrees for the processors and around 81 degrees so I don't think it's temperature related. I was using a black Desktop. Thanks to Jazzimus for the tip on the less black the better. I tried the Leopard Desktop and still got a few sparkles but when I tried the Tiger Desktop it was perfect right away. Thanks again guys.
