If they come from a half decent company then yes, you just need to download the drivers from the website.  of course there is always the problem with older hardware not getting a driver and software update, mice and keyboards should not be a problem but older graphics card may be a problem.

like a sappire radion 7850 graphics card

 

yes, AMD has drivers for windows 8 64 and 32 bit for their 7000 series cards
