[Wine] The .dll files

[1blah111111]

I have heard that there are some .dll files in wine that are faster than the ones in windows, i have a dual booting vista and ubuntu system, and i have a server that i'm looking to turn into a gaming pc, but i'm not going to buy another copy of windows, so i have installed ubuntu onto it, and am going to import the .dll files from windows, each and every one of them, but since there are some .dll files in wine that are faster than the windows ones, i obviously don't want to overwrite them just to use a slower .dll file. So i have to ask, which .dll files are faster in wine than in windows?
