Keep in mind that card choice depends on much more than just benchmark numbers. Movies will look better on a X1600, and of course SM3 games. A 7600GT is a great choice too. It sounds like you are still on AGP (as I am) so it depends on the specs of your entire system if you want to invest more in it, and how much, and how long you'll use it for current games.
You have to use the "grain of salt" test on these forums. It's all very subjective. Some people want the best visual quality and buy a high end card. Some will buy that same card and turn the quality down to crap mode so they get max FPS. You can't always tell where somebody is coming from when you read their advise.
In my case, I bought a X1600 last May knowing my AGP system was end of life for my uses. In a couple months it goes to my 8 yr old for that level of gaming, homework, and watching movies in her bedroom. Perfect for that use for several more years with minimal investment.
