For all I know, if you bought a legit copy of FO:NV, it comes with Steam.
This is also true for disc versions.
On install of NV, if you don't have it already on your pc, Steam will be installed and will automatically install all patches.
You shouldn't be able to install it without Steam at all, I think.
Unless of course you own a pirated copy?
