Which of these 2 cards do you think i could get the best performance out of? The 5770 is already factory OC but I can knock that up way higher. The 5830 I can also jump to get higher clock speeds. So which is better for games on a lower resolution, 1440 x 900 or 1280 x 1050 maybe a little higher . The 5770 is cheaper by like $30 but I can deal with it, as long as the 5830 is worth it. NOTE: I will be be getting second card once I know I'm satisfied with the winning card. Also, which card is better for crossfire? Thank You and thanks for reading my question!
