Strange positive findings..
Just installed W8x64 build 9200 trial .. Installed VM tools. connected GPU (4350)
board = tyan tempest i5400pw
I Didnt install cataylyst and did not use safemode monitor was connected.
Drivers were auto installed and all worked perfectly.
Installed drivers = WDDM v1.1 .
This was exceptionally easy. I must be exceptionally lucky with this board despite my LSI 8888ELP SAS not being recognised.
However what is curious is why in W8 these drivers work and in W7 they do not unless of course it is driver builds.
Next steps to test sometime in the future..
linux distros
N+1 GPU
PCIE extenders(splitters) to see how much I can pass through...
