your in the wrong topic,I think?
Each one is designed to suit your needs.
Theres a free one called virtualbox witch is like parallels and wmware combined but more to wmware.Read more abot
and download VirtualBox here:
Parallels is good for gaming.It comes with DirectX 10 support. vmware is better for OS tests,school work,and non-intensive 3D or 2D apps.I use wmware.
Gaming Ability Story:
If you like to play any games that aren’t available for the Mac, Fusion and Parallels’ ability to accelerate 3D graphics in Windows is a wonderful thing. With these latest releases, Parallels has taken a clear lead on the gaming front. I tested quite a few games and generally saw better graphics and faster frame rates in Parallels than I did in Fusion.
For example, I installed, a tool, with the same detail and resolution settings in both Parallels and Fusion, Parallels generated 40 frames per second; Fusion could manage only 0 to 11 fps. I got similar results when I tested each virtualization program’s OpenGL speed using Cinebench.
I also tried Simcity 5. Although it installed in both virtualization apps, I could run it only in Parallels, as the game requires10. (Fusion supports only DirectX 9.0c.) Not only did it run, it ran quite well. While Parallels' support for DirectX 10 is marked as experimental, it worked fine in my testing.
Virtual box i didnt test
Great for both of them. I watched home alone (good movie) on all of the products in a linux VM (including virtualbox) and it worked fine.
Go to http://en.wikipedia.org/wiki/Comparison_of_VMware_Fusion_and_Parallels_Desktop for info. No vituralbox info in there.Serch up "parallels vs vmware vs virtualbox"(no quotes) for that
I am a american and always in a hurry,so if i have bad english sorry.
VirtualBox is a very good application for virtual machines, so I wouldn't doubt to use it. However, as you want Windows for gaming, you need Boot Camp. Read > https://discussions.apple.com/docs/DOC-3321
To use Boot Camp, first read the requirements > http://support.apple.com/kb/HT5634 Boot Camp in Mountain Lion supports Windows 7 and 8 (in supported Macs). You have to get a full version of Windows 7 or, if you want and your computer is compatible, Windows 8. Then, open Boot Camp Assistant (it's in /Applications/Utilities) and follow the steps to install Windows. If you want all the steps to install Windows, read > http://manuals.info.apple.com/en_US/boot_camp_install-setup_10.8.pdf
I don't trust the free application, (like VirtualBox).
I would like to use a Windos only for gaming, becouse a Mac is always good...
How much does it cost VMware?
if you want to use windows only for gaming then you should not use virtualbox, vmware or any other virtual machine for gaming one should use bootcamp as virtual machine mean generic non 3d video card driver
and less memory
Are the same thing or are dofference?
Which are work better?
No one has really answered the OP's post so here it is.
The difference between the two is system resources. Parallels shares resources with OSX and Windows at the same time. Bootcamp gives 100% resources to Windows. The advantage of having parallels is that you can use both operating systems at the same time seemlessly where as using bootcamp you can only use one operating system at a time. They have their advantages and disadvantages as mentioned above but go with what you think you need the most. If you are gaming then I recommend using bootcamp. If you are just going to use windows programs that don't eat up a lot of processing time or memory then go for parallels.
