If you're disappointed with the quality/performance of Fusion 2, why would you pay more and blindly upgrade to 3 without actually knowing that it has measurably improved?
Either way, please report back after the upgrade. The 'new features' list isn't terribly compelling, but a genuine performance boost (on, say, a dual-core MacBook Pro, not just an 8-core MacPro) would be.
Model Name: MacBook Pro

I can confirm that if I turn on the GT video card that I can actually play DoTA (Warcraft 3) in Vista at 1024x768 with no skipping. Obviously it doesn't balk at anything less complex (like Linux development and testing, which is what I usually use it for).
Edit: The support for multiple monitors is also greatly improved. I tend to like to connect my MBP to a second monitor, throw the VM on it, then fullscreen it. Works great.
What are your hardware specs, and how much ram did you give the VM? I have a mbp that is a few years old with 4GB of ram, and fusion has never been slow. I did just upgrade to 3 and installed a Win7 image and it runs seemingly like bare metal.
