I do not hyeprbolize anything, it's the concrete personally tested as I have described above. For instance, for run really ok VM like W8.1 on host W7 x64 need 6/8 GB, otherwise it run better on host W7 x86 with 4GB ram. Tested.
Then if I need Win 32 bit for some programs, I don't understand why I should reinstall all over again, just to be able to use Workstation 11. I don't undestand this choice, for me it don't make sense.
