Doesn't matter, I have an Phenom 9750, and I'm not happy with it.
The different between Phenom and Intel Quad are not much. So, If you don't really care about OC and stuffs, go get a Phenom and support AMD, lols.
Phenom is just a stepping stone in my oponion. It is not a good product. It's a fair product.
If you are interested in energry saving, go with the "e" version of Phenom.
Or rather, just get an Core 2 Duo 45nm, it's extreme power saving.
