Currently I have Windows Server 2008 x64 installed on my machine. I'm about to reinstall when R2 comes out (few more days). Since I still remember all the tweaking with various device drivers, I'm thinking of installing an x86 version which has better Vista x86 driver support (that are also compatible with WinSrv2k8 AFAIK).
I have 4GB of memory which should be utilised without a problem on both platforms.
Would you suggest going to x86 or try the same driver hell all over again on x64? Would there be any significant speed issues? Memory issues?
I am/will also running several VMs of various kinds (x86 and x64). I know my hardware supports running x64 guests in x86 hosts already, so that shouldn't be a problem.
