From what I have seen the benchmarks were right around were I thought they'd be, remember they are only DX10 budget range alternatives, not right end.
Also, we are going to see benchmarks and additional information on the HD 2x00XT on the 23 of april. I'm hoping for some reliable benchmarks on games that are currently released, not Crysis or something else that we have nothing to compare it towards current hardware/games.
I personally think that ATI is going to dominate the lower end from what I have seen, but again I as well as no one else has anything to back up what we say, everyone is only assuming.
