You can get a hard copy of SH3 from Amazon real cheap these days, and if you go through the link in my sig Subsim will get a cut as well. Unless the 'SH5' in your post is a typo, don't expect SH3 to look anything like SH5. If it was a typo, GWX will make a difference in how the game looks, but there are also add-on mods that change it dramatically.

I meant how it looks in its folder on my drive rather than IN the actual game,sorry for my bad typing/explanation mate.

Did you try using the search feature?
