The motherboard in my old home server died whilst moving house and I have recently acquired a Dell Poweredge 2900 Tower Server.

It is great as a NAS but I would like to add some GPU power so I can do some video encoding.

I know I'll need a PCIe 8x to 16x adapter to get something reasonable to work with.

Would something like a Quadro K5200 work in this or would I be better off with something older such as a quadro 4000 or is that still too new?

Any advice or recommendations would be greatly appreciated.
