Best PCI-E video card?

[bns2000]

Like it says what is the current best video card that will work with Snow Leopard? I currently have a Nvidia GeForce 8600 GT PCI-E. And it dose work good until a game tries to change the resolution as the screen goes black. And the only way to get it to come mack is to reset the computer.

So now I am looking for the best PCI-E card to play games. And I need one that doesn't have problems like my current one. Thank Y'all for the help in advance
