Buddy the keyword for GPU choice would be the TDP rating, dell da-2 is at 220 watts so you would want a card with TDP rating less than or equal to 220 watts. Hope that helps

Ahh ok thats brilliant thank you very much. Is that all I need to mindful of then? Or does bandwidth come into play as well?

Thanks again.

Just a really quick question, I am about to press fire on ordering the exp gdc (express card version). But before I do I am just wondering about graphics card compatibility; what I was wanting to use with the exp gdc was a gtx760 would this be possible?
