There's a model number above the AGP connector. Thought of searching for that on google?
Google tells us it's from a company called GeCube.

Did it; that's where I got Info-Tek from. 😦
If you click through on some of the Google results you'll see listings for the same model number as "generic" (from Geeks.com for example: http://www.geeks.com/largePic_all.asp?invtid= … 8XTP-C3-box.jpg) and other inconclusive results. Doing an image search for a GeCube 9800XT yields a card that looks pretty much identical here:

But in GeCube's marketing materials and in reviews they generally show a reference design, like here:

I would not be surprised at all if this is another case of Chinese OEMs outright stealing FCC badge IDs, model numbers, etc for their own product. It's a lot more common than you'd think.
I remember reading somewhere that G80 and newer GPUs do not work well (or at all) with AGP, which is why there haven't been any cards newer than GeForce 7950GT released for AGP by even the most obscure vendors.
G70 and newer (which includes G80) are PCIe only - they are directly incompatible with AGP. GeForce 6 was the last generation of nVidia GPUs that had AGP compatible members (e.g. that's how the GPU interfaces with the system). nVidia produced bridge-chips starting with GeForce PCX to allow AGP GPUs to work on PCIe slots (which is how all of the PCX cards, and the GeForce 6800 are available as PCIe), and to allow PCIe GPUs to work on AGP slots (which is how 6600GT, 7600GT, etc work on AGP). I would guess poor sales are the primary reason the project wasn't continued - PCIe became pretty dominant for new systems by the time GeForce 7 was out, and the market for top-of-the-line AGP cards was almost non-existant. Not to mention, what AGP-based system isn't going to be utterly CPU bound with a GeForce 8800 or newer? (even with 6800 Ultra you're usually CPU bound)
ATi/AMD also produced a similar bridge chip, around the same time, but continued to ship AGP variant cards for a few more generations after nVidia - the HD 3850 and HD 4670 are examples of this. I would assume low sales were also a factor for the discontinuation of that venture as well.
As far as compatibility goes, bridged cards in general can have issues with some motherboards, and FWIR the ATi bridge has it worse. My understanding is that this is primarily with older motherboards (like pre-P4), but I've never personally run into major issues with my X1600 AGP (and that's the only bridged card I have). I've had more serious issues with bridged dual-GPU PCIe cards than with the X1600.
