OSX86 on old Xeon setup question

[zerohour]

Hi,

 

I have an old HP xw6200 desktop sitting on my desk being idle.  It has a Dual CPU dual Core Xeon (Nocona) with Irwindale chipset setup.  It has 8GB of Memory.

 

I could probably get Snow Leopard on the machine using the NawcomCD kernel drivers.  However to take advantge of the NVIDIA 710GT I need to go higher as the driver doesn't support Kepler cards in 10.6.8.

 

So to take advantage of the graphics card it would be preferable to get to say Sierra or High Sierra.

 

Could you say using Clover install something in the EFI folder to allow the system to set a 64-bit kernel.  I think what concerns me is the Xeon does not have support for  VT-x but it can support DEP.  I believe there is something about the NX bit (I have no idea what that is) but do later versions need UEFI if so could be an issue.

 

Any ideas if possible...
