The geforce 7300 gs in mainly a entry level card for a personal computer, it's simply a good choice if you want to play some games and you don't want to pay a lot of money to have a video card that does a lot in 3d if you really don't need it.
what do I need a card like that for ?
a) it's mainly oriented for people who use the pc for office work, it's ceirtanly not much useful on 3d level if you need to work with it professionally
b) it's at least 2-3 time better than a integrated one
c) it has a very low power consumption, so if you are searching for a good card that only use 16 watt in full 3d and 9-10 in 2d this one is certainly for you
