Kind of an expensive solution, but worth considering if the company deals with a lot of demanding business associates.Do yourself a favour and buy a i7 or multi core Mac with 16+GB of ram. That way you can run any windows platform at the same time using Parallels VM. Rad studio from Embarcadero has C++ and compile to OSX. Even does IOS and Android!
Check it out. I only have Mac computers but have XP, Vista, Win 7 and 8.1 all running perfectly with cutting and pasting between OS's.
