The X1800XL would be my choice too.
As for Quake 4; the newer cats have vastly improved OGL performance to be pretty much the same or better than Nvidia cards. See below..

Conclusion...
ATI’s pulled off one hell of an accomplishment. As shown by our testing, with one simple driver update, ATI’s gone from last to first place in Quake 4 performance. There’s a wealth of data you can glean from these benchmarks.
For one thing the RADEON X1800 cards really don’t begin to shine until you turn on 4xAA. For an example, let’s take a look at the Quake 4 numbers at 1600x1200 in high quality mode. While the margin between the X1800 XT and GeForce 7800 GTX was merely 5% in favor of the X1800 XT 512MB without AA, the margin opens up to a whopping 18% once 4xAA is applied. Meanwhile, the X1800 XL goes from finishing behind the GeForce 7800 GT, to outperforming it by 10% at 1600x1200 with 4xAA/8xAF.
[The X1800XL cards do seem to have better overclocks from what i have read too.]
