Umm well the processor you mentioned above can be overclocked to 3.4 ghz with only about a 1-2 degree C change. My friend did it and he said he liked it a lot. If you can spare the money i recommend the quad core 2.2 ghz, that can easily be overclocked to 3.5 with little temperature change aswell. But theres about a 150 dollar price difference between the two processors.
As for biostar motherboards, I don't really like them, go with either ASUS or GIGABYTE.
