the windows guest will see a virtual, emulated SVGA card, which is backed in 
dom0 by the qemu device emulator.
So, there'll be no acceleration, but it should be fast enough for 
administrative tasks.

Usually that should be no problem if you run only network services in your 
windows guest, but as a desktop replacement, it definitly won't be fast 
enough.

For desktop usage, you might be better off runing only windows directly on 
your hardware, and have linux run as guest on there. (coLinux, vmware 
player, ...)
(Or, of course, the other way round if you use linux more often)
