I want to buy a Nvidia Geforce 6800 OC graphics card and want to know if it will give me a better picture quality than the craphics card I have now. Now I just have a NV Geforce FX 5500. I know the 6800 OC is much better but I am asking because my flat panel monitor only has capabilities to produce 1024x768 at a refresh rate of 75 htz. It is a simple 15" Dell flat panel monitor. Would this graphics card give me better game play and picture quality with this type of monitor or would I just be wasting my money? Help would be appreciated.
