Did you try searching on the main page? The 5200 sux....if you have a 4400 or 4600, do not get the 5200. Depending on what games you play, the 5600/5700 may even be a waste of $$. If you can find a 5900 at a decent price, that would be a decent upgrade. I'd really have to think if I were going from the 4600 though....again, depends on what you're playing.
