But seriously, Intel makes some good products. They are pretty reliable and the RMA process is not as painful as others.
The benchmark that Indy posted favor processors that can perform highly threaded tasks well. The reality of it is that office workloads, word processing, email, AC, etc. are not highly threaded. The i3-2100 is about $120 and the 8 core FX-8150 (8 core) is $190. More cores does not always equal better. I'd take a i5-3450 quad core over that 8 core any day.
See this benchmark:

The motherboards I chose for high end are very pricey since they feature the new H77 chipset with native USB 3. So if you wanted to save some money go with the H61 with SATA 3 ports.
