I have a machine that's a couple of years old, but still functional; motherboard Asus P5Q Pro, graphics card Nvidia GeForce 9500 GT. It's had two monitors since day one, but I now want to add a third.
I've heard about DualHead2Go/TripleHead2Go, but at $380AU, I'm pretty sure that an extra graphics card is a more cost efficient option. It doesn't have to be the latest fancy-fancy. DVI is all I need (preferably dual, but I don't have the desk space for four monitors, so it doesn't matter that much), it's a work machine that's more workhorse than powerhouse.
Does anyone have any recommendations for suitable cards? Or advice on compatibility issues I may run into?
