S: GPU Board for Thinkpad W700 (any)

[Thomebau]

Hi,
i am looking for an affordable GPU board for a Thinkpad W700. Which one is equal, just needs to work in an W700.
As cheap as possible and with shipment to Germany (i am paying for shipment of course...).
Payment with Paypal is my favorite for international transactions. I am going to pay the fee.

For reference a link to my account in the german thinkpad forum with nearly 7000 posts ^^
