I can definitely notice the difference and I would never use VGA on an LCD, though it depends on the equipment and how trained the users eye is. One thing to keep in mind is, DVI will always be better, it certainly won't be worse, as another user pointed out it bypasses 2 unnecessary conversions. With a VGA cable, you start with a digital signal, then it gets converted to analog at the RAMDAC, then back to digital inside the monitor...some video cards/monitors do this better than others, but it doesn't make much sense when you can do digital all the way. The colors will be more accurate and the picture more crisp with DVI. Get a cheap DVI cable(a more expensive cable will do *nothing* when it comes to short distances.) If you don't notice the difference, you aren't out that much and at least you know you have the best config. Hope that helped.
