Help with buying a new motherboard

first of all please excuse me if this is in the wrong forum and if what l say loose you as l am new to all this. l want to build a computer that has more balls than a wild pack of dogs. l have been told that if l buy a supermicro X7DBE+ Motherboard With Extended ATX which runs dual processors, front side bus speeds of 1.333Ghz, Front side bus uses a 64 bit wide 1333 Mhz data bus that transfer data at 10.7 Gb/sec for a total bandwith of 21.3 Gb/sec. Total memory bandwith of 32.0 Gb/s for DDR2 667. And build the rest up from the motherboard l will never need to upgrade.This all means nothing to me so l thankyou all who help in advance. Also does running dual processors mean that you will have twice the speed.
