I have an older Dell 8250 system with a Radeon 9700tx video card with a DVI output. I just purchased an HP 19B LCD monitor with a DVI input. I currently have it hooked up anolog and was going to purchase a DVI-D cable from MonoPrice.com and was wondering what to expect with the quality of the picture compared to the anolog hookup I have now. Also, any recommendations on what video driver would be best to use?
