Using irqpoll pcie_aspm=off selinux=0 as boot parameters and setting powermizer to lowest performance setting ( to prevent the gfx card from heating at all ) , disabled openGL flipping , the crashing behaviour has changed.. The card no longer drops from the PCIexpress bus but instead it produces some more revealing messages ..

I changed my xorg.conf Section “Device” to
Section “Device”
Identifier “Device0″
Option “Coolbits” “1″
Option “RegistryDwords” “PowerMizerEnable=0×1; PerfLevelSrc=0×2222; PowerMizerLevel=0×3; PowerMizerDefault=0×3; PowerMizerDefaultAC=0×3″
Driver “nvidia”
VendorName “NVIDIA Corporation”
EndSection
to set the graphics card powermizer setting to always use the lowest setting as a test but since it heats up a lot less , it is more quiet and the onboard electronics will probably last longer I am thinking of keeping it configured that way..! 
NVidia forums remain under “maintenance”
nvnews.net has disabled new registrations..
