Last week I picked up a bargaintastic Dell Dimension 8400 which has just arrived at my parents' place. It turns out to have a PCI Express Nvidia GeForce 6800GTO card in there, which has 2 DVI outputs and that's it. Which is rather a bugger. It was my intention to use it to replace my main PC so it really needs TV out, preferably S-video. Before I decide whether to ship it out here or put it on ebay, would there be any problems (compatibility or performance) with installing an additional PCI graphics card which will give me TV out while retaining the 6800 for gaming?
