maybe he's inquiring about how it will perform (fps wise).
You'd easy get 55-60 FPS on low settings. i play on fair/mid and get 40-50 most of the time on a 2.0 Ghz alu macbook. you can put all the settings on high and probably get 20-30 FPS at least. (this is all at native resolution)
It'll run quite well, but particularly if you intend to play the WOTLK expansion you might wanna turn some graphics settings down to avoid dipping into the single digit fps at hectic moments.
ty, didn't know if the 667 memory would impair this, that's what I needed to know. Plus I only play Burning Crusade, waiting for WOTLK to get cheaper first.
