Whic VGA card to choose

Check these charts to compare your cards, but I would always choose the newer card, which in this case is the 5770. Before making any purchases, always check Tom's charts, you'd be surprised sometimes what you see!

Also, please be sure to check the forum first before you ask a question, as there is a similar thread about half a page down
