Some preliminary feedback:
1) Graphics performance is very good. It is not as good a native, but significantly better than before. The Windows index now nets a solid 6.0; I know this isn't really a determining factor, but it's a good start. I don't play many games, but for Source games I can get on average about 60fps at 2560x1600 resolution. No I don't have Crysis or those newer games to run.
2) Like my first impression, it is faster. I mean it may just be that I feel it's faster when it's not, but boot times are lower for my VMs. Applications launch quicker. I have allocated 4 CPUs, and 4GB of RAM to the VM, so that may be a contributing factor. I used the same allocation before with Parallels 4.
3) The full desktop mode is amazing. I think it's a great way to go to a Mac and still use your computer as if you're running Windows. I'm sure some people will frown upon that, but maybe you can convince your boss to update you to Mac next time at work? They did have this in VMWare Fusion, but it didn't feel as fluid. Very smooth and seemless. They have the whole Linux Compiz like cube when you switch from Window to Full-screen mode.
If anyone has suggestions on other things to run to test, I will gladly do so. I will probably buy Fusion 3 for Mac since it supports 64-bit kernel extensions now. Will run that side-by-side so see which is faster.
