For $100 you can get much better cards than these!

If you are not in a hurry, check hot deal sites like

and you might be able to get some awesome card.

Recently, there was a deal for nVidia FX6600 for $99 after rebate. This card is 10 times faster than any of the cards you've mentioned! I got my FX6800 for $130 a couple of months ago. No comparison with my old Radeon 9600, which was fster than Radeon 9250 you've listed.
