Yes, a 32 bit version of Windows 8 is available. I would only get it if you NEED a 32 bit copy though. Valid reasons for needing it include: CPU doesn't support 64 bit instructions (which like you said is pretty rare these days), or you have a Mission critical application doesn't work properly under a 64 bit OS (getting rarer in occurrence by the day). Otherwise go 64.
I really hope this is the last mainstream version of Windows that Microsoft makes which includes a 32 bit version. It really is time to move on.
