All of them? Depends on what you mean by low performance.
E6300 is certainly the most modern CPU there, but probably a toss-up with the D. Both are dual core 2MB cache CPUs. The D runs at 3Ghz, the E6300 at 2.8Ghz, but it has the faster FSB and more modern architecture, so probably comes out ahead.
Really depends on the rest of the platform you have available. DDR2 800, possibly DDR3 1066, and the GPU.
