Thanks Lee, Neil and Gregg, Nobody can really say what one needs. Adobe have minimum requirements but then it depends largely on the complexity of work one is doing. I am making videos mainly for my own fun and I think any of the graphic cards I mentioned will do the job. I think I will go for the GTX 570 as it is on the list of cards approved by Adobe.
