I need to know which of these cards I should choose from. I have $400 to spend and need two cards including shipping. I have been through with ATi cause this X600 Pro isn't holding up against anything I throw at it. So, which card will be the best?
eVGA GeForce 6600GT $200.99
eVGA GeForce 6600 $152.00
Sapphire Radeon X700 Pro $171.49
eVGA GeForce 6600GT $200.99
eVGA GeForce 6600 $152.00
Sapphire Radeon X700 Pro $171.49
