Hello..Im looking to buy a Pci Express card for gaming.Im looking for something in the range of $100-$150..Im sure i cant get nothing that is great for this price but i need to know what are the best cards around this price range? I prefer Nvidia but if a ATI card will give me more preformance then i would get it. As long as i can play some newer games on medium settings or so i would be happy..Thanks
