I have a topic in here about replacing the 5500. It was a good video card for the nearly 2 years I have had it.....but, I am finding that it is just not up for playing these next gen games. It runs F.E.A.R..but just barely. It wont run AoEIII at all, and I did not buy the new BF because of this video card and it's inablity to run these newer games at a level I/we want. It runs WoW fairly flawlessly but with 90% of the bells and whistles turned of, and for me this is a problem.
It looks like I will be going with the 6800 (more investigation needed) and I'm praying it will play Oblivion.
