Having just received my Vue 4 Pro, I asked e-on what graphics cards they recommend and they said that any Quadro based card was a good choice - I checked them out but the prices are very high (average 2000):( I am now looking at the top-of-the-range Asus card (400) but I don't want to make the wrong choice so I'm holding back until I'm sure it will work ok. Some time ago I bought the Oxygen GVX1 (I don't think they make it any more) it was loads of money and quite frankly it was dissappointing to say the least. The point that I'm making here is that the money you spend does not alway's mean you are getting a good card. Let me know if you find a good card :)
