to answer you question on has to compare the HD 630 to other cards, using passmark as a reference point it gives it a score of 1,307
first chart compares that video card to current models
second chart give you an idea where it stands in the great pile up of video cards out there.
in English is a little better than an ATi HD 6750 and less and a dual 7xxx series video card
it will run call of duty MW2 at about 150FPS if you re optimize the snot out of the configMP.sys file.
it will run poorly about 30-40fps start trek Online
its not a great video card for new games....
