Ok, this guy is asking questions specifically related to ATI cards, the atlantis, pro, and xt , and everyone just comes in and says 6600GT or next generation. He even mentioned that he preferred to have the ATI cards because he was on a budget, yet people still came as said 6600GT, next generation. I think this is getting way out of hand.
Edit: Btw, stick with your current video card. The extra money will not give you noticable performance.
