A very enjoyable article. Few points:
1. While the benchmark the author kindly put a lot of effort to make is nice, I believe it's much worse than the worst case scenario for most ppl, most people play online against human opponents or play against the AI in the single player campaign or to get some training before diving into multiplayer. IMHO it should have tuned down a little or the GPU/CPU recommendation should be stated with less certainty. Readers should put that well in mind.
2. ATI released CCC10.9 after the article was written and it is said to improve the performance while AA is on, but I really have to test this to confirm. If anyone tested the new driver please share the results!
3. For those whiners about not including their hardware in the piece: STOP! It is near impossible to include all the hardware out there, besides I always noticed that Don is somehow limited on the hardware side, so he only used what cards Gigabyte offered, and that was clearly stated in the article. As for the CPUs he did a comparison of 1, 2, 3 and 4 phenom 2 cores, so this should give you a good idea how the game scales with CPU cores and it is obviously not threaded well enough to make use of Phenom II x6 6 cores.
Feel free to thumb me down!
