Yeah I just went around reading this site benchmarking and comparing data between the two and 64 bit seems rather worthless unless you push your system to extreme limits, like 4 gig + of ram and other such extremes before you see real differences. Before then it's not noticeable by much and in many cases slower.

So my big question comes down to this. Will there be issues on my 64 bit capable processor in running a 32 bit OS? My brother tells me it will suck, but he also didn't know ANYTHING about the changes to the interfaces on hardware and the change in wires and connections.
