Many games are still CPU bound. May applications are still CPU bound. Notice all the threads lately about how applications have so much more latency now than 20-30 years ago? Virtualization does have impact, and games still max out the hardware available to them.

If this is 100% seamless virtualization that doesn't make anything noticeably slower, it might be acceptable for business users. I doubt it's going to have zero impact though...

I highly doubt it's going to fly for power-users and gamers.
