I'm an AMD fanboy, so I recommend AMD, but I can't say for sure.

The nice thing about the procexp logs I'm asking for is that it gives a lot of info that is useful to the trained eye.

For instance, if you have a very high CPU usage with a low amount of context switches, you want more speed and L2 cache. If you have a high amount of context switches, however, you want more cores. If both of those numbers are reasonable but RAM is high, you may want faster / overclocked / more RAM. If your GPU usage is low but the GPU memory usage is maxed out, you know the memory of the GPU is limiting it and you want a GPU with a higher memory threshhold.

And, with all things determined, you probably want some watercooling before your PC melts and you jump from window
