I think I have tried everything that is possible to fix this issue and I have found a workable and permanent solution. Let me tell you first of all I signed up for these forums just to post this.
These are things I have tried before anyone reads any further in an effort to prevent people from trying them on their own as they seem useless for the most part.
2 totally different pc's (Mobo, proc, everything different)
2 different brands of 5870 (Sapphire and Asus)
12 different monitors (different brands and ports)
7 different adapters (from displayport to basically everything)
8 different drivers
2 different o/s installs (including fresh reformatting on both as well so 4 technically)
many, many different cables
different peripherals (mouse, keyboard, etc)
every possible setting I can think of with regards to windows 7
every resolution from 1920 x 1200 to 640 x 480 and different refreshrates up to 120hz in one case
So much thought and troubleshooting and reading it will make your eyes bleed
So, after all that it was a 5870 bios flash that fixed it.
This bios from ati changes the voltage of the display port slightly and that keeps the monitor from going into power save or standby or simply losing sync.

There may be a bios for your specific card in there but it's up to you to verify if the voltage is changed or not. Using that bios and a few guides on exactly the safest way to flash the bios without bricking some cards I got it working. The primary guide I used was here

In the end I have had this fix 5 different 5870's of different makes and models. All have reported no issues in several days and in one instance I do know he has overclocked it slightly as well.
My own stable rig atm runs 3 1920 x 1080 monitors all throgh dvi. 2 natively and one using dell's dp -> dvi active adapter found here. http://accessories.dell.com/sna/products/Cables/productdetail.aspx?c=ca&l=en&cs=cadhs1&sku=330-5521 A sapphire brand 5870, and the rest seems to make no difference so as to mention it would be useless.
I've spent weeks with this issue and hopefully my troubles have enabled some of you to fix your issues. Bear in mind however that I take absolutely no responsibility should somebody attempt to flash the bios on their card and mess up. Use this fix at your own risk. Let me know if anyone else has had success with this as I have.
