I agree with ehkart, the 5200 is a horrible performer and in no way shape or form is it comparable to a 9800pro, or even a 9600... infact it's not even comparable to a 9200 either.. the primary reason can be attributed to the fact that nvidia decided to slap SM2.0 on a card that can't handle it, and althrough the 9200 only has SM1.3 support, since it dosent have to handle the extra eye candy, it runs better than the 5200..
$20 is a good deal, but don't buy either if you plan or using it past solitaire.
