I hope I can keep this within the topic and might even help the original poster's decision. Since I'm a noob to the benefits of Opteron, when I look at the spec sheets, I see the Opterons run at 1000 mhz bus speed, but when I look at the 3700 it's at 2000mhz. Both have 1MB of L2 cache. Stock speeds, the 146 runs at 2.0 ghz and the 3700+ runs at 2.2 ghz.
I'm inclined to go with the 2000 mhz and 2.2 ghz, thus picking the 3700+.
Again, that's just me looking at the numbers as a Joe Schmoe consumer. Aside from the OC potential, why is the 146 a better CPU? I'm understanding the numbers as running slower with 1000 mhz.
Another part of the question is, if I OC the 146 up to 2.2 ghz, wouldn't it still be a slower CPU?
