which is better windows 7 or windows vista for nba 2k11?

i want to know what OS will be better for nba 2k11??someone please help because i have a low PC spec and i dont want to drop my fps..any idea guys and suggestions?

i'm not sure at all.. but maybe it's windows 7 because vista really sucked for gaming (at least that's what i've read and heard).. with windows 7 i havent really had any problems yet

i've tried both already and i can say, based from my experience that vista is too slow compared to 7. some may say that it depends on the user. but for me, windows 7 it is.

Vista is much heavier compared to Windows 7. If you will use W7 for NBA 2K11, your gaming experience will be smooth compared to Vista.

thanks guys for the help and tips..
