Hi Jacob- > Thanks for your support. In regards to a video card, would there be any > difference in IDV performance with a high-end video card versus an average > video card? Would an AGP video card work as well as a PCI-Express video card? The more memory on the card, generally, the better performance. However, it really depends on the graphics driver. I'm not sure you'd see much of a difference in the IDV between the two architectures.
