I now purchased a Tyan Tiger K8W (s2875) with 2 x Opteron 244, 2 x 1GB Kingston reg. memory and an ASUS Geforce FX 5900 graphics card, which should work fine. (with the Nvidia binary for 3D)
Almost the same config as I've got. I would recommend getting 4 sticks of memory, then you can get the mobo to interleave nicely. I've got the 5950 video card, it works great with nvidia's 64bit drivers. I wouldn't even sweat any 32bit GL software either. You'll have to run those with software GL, but I was still getting the same performance as the ATI9600Pro in my UP Athlon XP. The second processor handles the software GL load very nicely. On the hardware GL side, the 64bit equivalent apps are running anywhere from 4 - 10 times quicker.
