I just got a GTX 770 and it gave me free games.
I have a voucher for the games in the topic title, they come together.
Redeemed here:

Steam games I have for trade/sell are:
Assassins Creed
Assassins Creed 2
Assassins Creed Brotherhood
Dragon Age: Origins Ultimate Edition
For the voucher games I am looking for around $80 or a new Zowie FK mouse, which is between $60-80.
