[fighter2012]

Hey Guys,
i wanna know which one of those cards is better with the new graphics games

1. Nvidia 630 GT 2GB DDR3
2.ATi HD 6450 1GB DDR3
3.ATi HD 6570 1GB DDR3
4.ATi HD 4670 1GB DDR3

btw i have a 300W PSU... which limits my power someway.

HD 6570 is the best out of the list, but it isn't really good for new games - it will barely play them.
