I have a Velocity Micro gaming PC with a 3 gb RAM, AMD Anthlon X2 64 processer, and 500 gb Hard Drive. And i think that it is about time i got a new graphics card and was wondering which graphics card would be the nest possible card withen a price range of $0 to $200.00 and more than 512 megabytes of video memory. It also must be able to play the new Aliens vs Predator game that is released on February 16 2010 with no problem what-so-ever.
