I'm replacing the 8800GTX card on my XPS 630i. I've narrowed it down to either the GTX 460 or GTX 560Ti. Any thoughts on which one is a better fit for my system? Looking for the best bang for the buck without breaking the bank. I'm leaning toward the GTX 560Ti, but am wondering whether it's too much capability on an older system?
