The 4770 is the more powerful card of this selection. However, if you are purchasing at the $100 mark your best option is an ATI 4850--available on newegg for $99.
If you would like more detailed advice you should post your system specs-including power supply, as well as your monitor resolution.
Also-please limit your use of caps in the forum. :-)
