http://www.newegg.com/Product/Produc...82E16814127303 is also a pretty good card. 512 Gddr4. depends what res, though. ATI normally perform better at a higher res then nvidia, but if its regular ~1024 res then go with the nvidia. 1920, go with ATI
http://www.newegg.com/Product/Produc...82E16814161060 is better then both BUT no dx10
http://www.newegg.com/Product/Produc...82E16814133186 again, no dx10 but still a very good card. you can run vista without a dx10 card (i am), it just that you cant run games in dx10. dx10 isnt that popular yet, so you might want to go for a dx9 card.
http://www.newegg.com/Product/Produc...82E16814150197 is also quite a good card
