What Nvidia card closely matches Radeon 9600 performance?

[halfadder]

The Radeon 9600 seems to be a nice mid-range DX9 card. The Pro and XT versions can play Doom 3 nicely, but it's still no GF 6800 or even Radeon 9800.

My question is this: What Nvidia card(s) perform similarly to the Radeon 9600?

5700 Ultra is its closest match (refering to the 9600XT, not the plain 9600)
