Gigabyte Z68MA-D2H-B3, Z68 chipset, PCIe Gen 3 16x PCI slot, (which is 
the slot I have the card in).

The video card is a Gigabyte GT 1030, not sure how to pull the specific 
model number from remote ( not at home at the moment ). I'm reasonably 
sure its: GV-N1030D4-2GL.

The processor in this machine is a lowly i3-2120T, which only supports 
PCIe Gen 2, but considering were using the card to handle the video 
decode, I wouldn't have expected the bus speed to be that much a bottle 

Again, I don't have a lot of 4K content, so while I'm a little 
disappointed, it isn't costing me any sleep :-)/
