Remarkably well done. The graphs were among the clearest I've ever seen here. That said, I'm not yet sure where to fit in some conflicting thoughts. It's a great point of reference, no question about it, but I think some conclusions must be made cautiously. I'm really looking forward to the AMD pairings, because it will really show more of the boundaries of the strategy "less on CPU, more on GPU" that is often taken when building a gaming rig.
I was a little disheartened to see how poorly my HD4850 does with these games, but since I have other information in my "index," I can offer a couple of pinches of salt: first, if you're willing to lower settings even a little, Tom's own articles on mainstream gaming show that even a HD4670 is competent for playing many current titles. Second, if you're still playing a favorite game that is a year or three old, lesser hardware does just fine. For example, the sorry showing of the HD4850 here did not suddenly drop my frame rates on Guild Wars at 1680x1050 below the monitor-pegged 60FPS. For what I play TODAY, an upgrade is not warranted.
Still, if a new game out there (please test Dragon Age: Origins!) needs a beefier card to play with high settings, this article would very clearly help me convince my wife that I need to spend $300 on a GPU to enjoy my game(s).
Finally, I realize it will be a much busier graph, but if possible it would be very useful to see one that has both AMD and Intel CPUs on it. The e6300 CPU and HD4850 GPU appear to be [mostly] losers, and I suspect the AMD X2 will be the same, so those might be left off if it adds clarity.
And, like everyone else, I am looking forward to the update that includes the HD5000 series in it.
Suggestion for the GPU OC graphs: instead of a line, consider a ribbon, with the lower border the performance at stock, and the upper border the performance when overclocked.
Thanks again.
