W7 is dx11.
As for 4890 yes and no. dx10 cards can use parts of dx11 but not full compatibility. That will require a new gfx card IIRC
As for do you need it, do you need any of these features. Remember xp mode is an xp virtual machine and not comparability mode. HP has the compatibility mode.
Thanks for that.
I preordered the Pro edition yesterday to make sure.
Glad I did, as Remote Desktop Hosting is something I'll want, and I'm also hoping the Windows XP virtualization will support USB devices. My PVR allows files to be transferred to and from it via USB, but only has 32bit XP drivers available*, so I'm hoping that with Windows 7 Pro I'll be able to use the PVR inside the virtual XP machine. I'm not getting my hopes up however, it doesn't work with VirtualPC, nor work properly inside Sun VM.
* there is a way to get it to run in Vista 32bit, but again, I run Vista 64bit and will be upgrading to Windows 7 64bit.
Vin.
