As for 'not wanting to get a new motherboard' I wouldn't worry too
much (depending on why you are concerned ;) ). I have found a couple
of outlets where you can grab motherboards with the chipsets that
support unichrome on them for ~20-30 bucks (that's less than the cost
of an Nvidia standalone) that also have a few other niceties
integrated. I know, most of us are probably anti-integrated, but it
really isn't so bad for 25 bucks ;)
Go hunting for a board to suite your needs before ruling it out, you
may be happy with your find.
