performance md11 vs. B747

hi,i just noticed that on the product pages you stated different system requirements for the B747Fsx and Md11Fsx. For the queen you wrote a minimum of 3.0ghz, for the md11 only2.0ghz. does that mean the md11 has a better performance in fsx than the queen?i have still only my laptop (1.86ghz, 2gb ram) which can handle fsx with asx, rc4.3, lds767, DA fokker and the maddog2006 ok. i don't use the queen because somebody told me that it takes much more frames than the lds767. it would be really a dream to fly the md11!otherwise i just have to wait until i finally can upgrade my pc.thanx, chrjsps: is there a chance to try the product and give it back if it doesn't work?
