I was in the same boat as you until I decided to upgrade my entire computer.
My R9800 pro died on me after 4 years of SOLID service running at 400mhz OC. R.I.P.
x1950 Pro seemed to be one of the best AGP options. It ran everything really well, even COD4 and WoW at respectable 30fps on med-high settings. I only used it for about 2 months before getting the new rig. I doubt D3 will be out till either this time 2009, or Q4. Gives you a lot of time to go to a PCIe rig.
edit: my old PC is/was P4 3.0ghz HT 800fsb, 2gb DDR400. Similar to yours but a bit higher bottleneck threshold.
