Parallels ver.5 with MBP i7 question

I have 4GB RAM on my C2D Intel iMac (the maximum it supports), and allocated 1GB RAM to Windows. It works quite well - but those two applications will likely not perform well in Parallels, even if you give the VM 4GB of RAM.

I also have a C2D iMac with 4GB RAM. This month I installed Parallels 5 with Windows 7, and got the products to work. Installation was easy. On the downside, I couldn't get Parallels/Windows 7 to run the Blue Mars client (3D virtual world platform using CryENGINE™2 powered graphics), so uninstalled Parallels and the Windows 7.

Set up Apple's Boot Camp instead and installed Windows 7 under Boot Camp. Blue Mars client runs without any problems. Running this software was my main need for Windows 7. So I vote for using Apple's Boot Camp to run Windows 7.

After using both parallels and vmware I went back to boot camp. I do a lot of auto-cad stuff and the mouse wasn't as precise when running in virtual machine. I have used both xp and win 7 64 (currently running boot camp) in a virtual machine. Go with boot camp if your doing 3d stuff. Need as much ram and video memory you can get.
