So I bought a new i7 iMac last week, the 27" 3.4 GHz with 6970M GPU, everything seems ok apart from Wow. First use in anger was in a raid last Sunday and I was getting major graphical pauses during BWD, I noticed that the recommended tab on graphics set everything to low or fair with projected textures off. So i ramped everything back up to my usual settings and that was when the pauses really started. My previous machine was also an i7 iMac, the 2.93 GHz with the 5750M GPU and that ran Wow perfectly with the recommended tab putting most settings on high. So what I don't understand is that the 6970M GPU is much more powerful than the 5750M and yet I'm getting much worse performance. Has anyone else who has bought a new Sandybridge i5/i7 iMac found a similar experience in Wow? Is there a way of testing the GPU in OSX to see if it's knackered? Cheers in advance.
