PNY nVidia Quadro 5000 GPU:
2.5GB memory

1x 6pin power input

1x DVI-I dual-link

2x DisplayPort

Quadro G-sync II card:

used in configurations needing g-sync, genlock, frame lock, swap-sycn, or house sync features.

Compatible with NVIDIA Quadro 6000, Quadro 5000, FX 5800, or FX 4800.

The most modern Quadro cards use "quadro sync 2" cards not "g-sync 2" cards. Nvidia is really a pain with their names.

Buy together or separately. Make an offer if you want to buy more than one.

Used parts from secondhand servers. Still run strong - certainly capable of gaming, or running a home server, or just doing business work. I also have CPU/motherboard combos, and power supplies -- see my other listings.
