Is 256GB enough for Windows dual boot

Was close to pulling trigger on 256gb model but then got to reading some threads that talk about it being useful to have Windows on the deck for some games that don't work or don't run as well under linux. Now I am wondering if I need to spend more to get the 512 or will 256gb still be enough to dual boot? I plan to keep most games on MicroSD so internal space for games not an issue so much more the shaders which I know can be a bugbear and why I didn't even consider 64gb.
