No, not really, that might not even be any better than yours. See, it's dead last in this benchmark:

If you find a card, do a google search for benchmarks, which are performance comparisons to other cards.
So like I found that page by googleing "radeon 9250 benchmark" or you could try "radeon 9250 review" because youa re gonna have to do some research to find the card that best fits your price range.
If you are gonna buy online, I definitely recommend
