Dual video card help
Crazy Cooter:
You might run into problems "mixing" cards that use different drivers. IIRC, the AGP should be set as the primary.
ChadTower:
Thanks for the tip... how could you use the same drivers for an AGP and PCI card, anyway? Wouldn't that necessitate separate drivers most of the time?
ChadTower:
Um, yeah. The 3DFX card I've had sitting in a drawer all these years appears to be neither PCI or AGP since it fits in neither slot. The PCB date is 1999, so what the heck interface could this be? All I could come up with is PCI or AGP and it's sure as hell can't be ISA.
ChadTower:
Hrm... the part # is 210-0364-003, and apparently it's AGP 2x, according to:
http://www.falconfly.de/identify-3dfx.htm
Is the pin configuration different for different versions of AGP?
ChadTower:
Okay... from a FAQ about my machine:
--- Code: ---Does the 400SC have an AGP slot?
A: Of course! (The AGP slot is, however, not supported by Dell.) Picture here and diagram here. The AGP socket is keyed for universal 0.8v AGP cards that comply with the AGP 3.0 specification or 1.5v AGP cards that comply with the AGP 2.0 specification. The AGP connector supports 8x, 4x AGP 3.0 add-in cards operating at 0.8v, or AGP 2.0 add-in cards operating at 1.5V. There is no support for AGP 2x operation or legacy 3.3V AGP cards.

So, looks like if I want dual head, this is what I need to get. I'm so out of touch with video card interfaces, etc. Does anyone have a specific, inexpensive card they'd recommend? I'm not a PC gamer, and don't do anything overly taxing with this machine other than remote access to work, net stuff, etc.
