VirtualBox or Parallels: Great Visualization I decide to choose two virtual machines. VirtualBox and Parallels.

Issue:
Which of them good enough for visualization tasks? (GPU, games)

I want to install on my Macbook Pro 2011 more RAM: 4gb -&gt; 8gb.
After that I want to install on virtual machine Win7 or Win8 with 4-5gb RAM.

As GPU I have AMD Radeon HD 6770M 1024 МБ

So, which of (VirtualBox or Parallels) give me more visualization performance?
It depends on what kind of thing you want to do, but neither will be a good enough option.

If doing GPU-intensive work, your best and probably only option is BootCamp, and then Parallels.

VMWare Fusion would work, but it's slightly behind Parallels. VirtualBox is worst, but it's free.

As for whether you want Windows 7 or 8, it really depends, Windows 8 start up a lot faster, but consumes quite a lot more resource than Windows 7 until I turened off some useless services.

Here's a link you can check out if you like to see some benchmark result.

And here's a even better one that compares all three virtualization software against Boot Camp.
