I've just assembled a new computer, but I am still using an old 15" lcd monitor. The processor is an i5-750 and the video card is a 4870 1gb card. What resolution wouldn't be too much for the video card to handle. I will be using this setup for gaming. I am thinking 1680x1050, but that is just guessing. I am currently using 1024x768 for all my games. Thanks in advance.
