I have an iMac G5 (non-intel) with MS Virtual PC for Mac -- I bought the software primarily to use the PC version of Quicken since the Mac version is less than adequate. However, the response time is very slow and I found it unpractical. How is the response time w/Parallels? Is their a benchmark comparison vs. Virtual PC? Also, I understand that Parallels desktop will only run on an intel mac- please confirm - thanks!
