I recently bought the Radeon xfx 4890 and threw it in my computer because my xfx 8600gt died. I was wondering if the card I bought my be a little to powerful for my processor and if that's the case does that mean I am not using my card to its full potential. I have never really OC'd but am willing to try bumping my processor speed a bit to see if that helps. What do you guys think?
