I am running both versions on my computer with not too many problems. One thing I have noticed is that SmartSound music options are completely blank in 9. It's fine in 11 though. Sorry I can't help you with your computer specs. I will say this though, if 11 is running fine on your current set up, no crashes etc..., then I wouldn't worry about it. On my notebook I always get a message saying that the CPU is working overtime, but I haven't really had any problems because of that though.
Good luck!!
