Its just that in all benchmarking tests HD 6850/6870 seem to do almost as well as GTX560ti except that they are 50 euros cheaper.

If your trying to save a few bucks, get the 6870. They do make a 1gb. model of the 6950 thats like 20 bucks cheaper.

This leads to another question: If I choose the gtx560ti, should i take 1gb or 2gb?

If your not running higher then 1920x1080 the 1gb will be fine.
