The card I installed later was a Geforce GT 240 from Gigabyte, I also needed to relocate the capture card to make room for the second graphics card. After booting into Windows the new hardware was detected and automatically installed the drivers needed. But a couple of things were also installed:
* Xeon(R) processor E3-1200 v2/3rd Gen Core processor PCI Express Root Port - 0155
* Intel(R) 7 Series/C216 Chipset Family PCI Express Root 3 - 1E14
I'm not surprised for the intel 7 series stuff, but as far as I know Xeon is for servers and it caught my attention, so far I haven't found an explanation for this, maybe you can find or have an explanation?
The desktop chipset is basically a crippled version of the server chipset.
If you go into your device manager and look under System Devices you'll find it full of xeon chips and bridges. The system I'm on just now is a i7-3930K and it's got a whole raft of Xeon E5/i7 devices.
