Hello, I haven't used any of the two, but I have tried vmware player and workstation... I am sorry I do not mean to advertise the other company. The reason why I am here is because vmware crashes "A LOT". (3D acceleration problems) I have and will need 5 or more virtual machines with multiple extensive graphics need for video games. Is the workstation enough? or extreme is an overkill? To be honest, the extreme is very expensive... and I am hoping that someone can tell me that Parallels Workstation would be enough. Thanks a lot!
