I would personally just wait until you have about 125-175 because sub 100 dollar graphic cards usually are really low end and won't be able to run stuff.
You'll just end up having to buy a new one in a couple months.
But I guess it entirely depends on what type of games you're going to be playing, if you're going to be playing crysis then the 430 can barely run it past 45 fps on minimum settings, which looks like stuff.
