Ok well there are some extra features in the more advanced ones you can decide to use and if you actually use them they may take up a tiny bit more ram and a tiny bit more CPU (like 1% maybe?). But as a stock install of each, no, they are 99% identical.

Well the difference would be so minimal you wouldn't even notice it. Unless you have low disk space, Windows 7 Ultimate will use more and fill your Hard Drive which could slow down your computer - An example of this is installing all 34 Language Packs - that will use up quite a bit of Disk Space.

Carlos15. Just stop. It doesn't matter which edition you run. THEY ARE ALL THE SAME. If you can run one, you can run the other. The only difference between the editions is the extra software features that have no effect on performance.
Pick the operating system that has the things that you need or intend to use and get on with your life. Their is probably some one with a chart and graft to show you some difference but you and your computer will never know the difference.
