dvi and hdmi are pretty much equal.
a good quality hdmi-dvi cable should eliminate the issue nin-ha has. i've seen reports of poor image quality with such cables on here but i've had no issues with the evga one supplied with my video card.
if your pc outputs hdmi and you have a ps3 then maybe you should have went hdmi. if your pc outputs dvi and you do not have a ps3 then you are fine. if you have dvi and a ps3 then its a toss up.
in any case...it should not be an issue at all as suggested above.
