Which version of VISTA64 do I need?!

[FwoGiZ]

Which version of Vista64 do I need for that computer. I ll use it mainly for online FPS and home theater.

evga780i
E8400 oced 4ghz
4x2gb ddr2 pc2-8500 1066mhz
barracuda 7200.11 500gb
ocz gamexstream 700w PSU
Logitech Z-5500 Speakers
Samsung 226bw 22in monitor

I think that basic doesnt support dual CPU right? but E8400 is core2duo but its still a single processor so im kindo mixed up...... should i take other features in consideration?

Tx in advance for ur opinions/expertise

home premium is more than adequate, ultimate has a few extras that are somewhat nice but by no means needed - don't even consider basic. Business is good but I think it lacks Media Center, for your home theater.

Home premium or ultimate if the extra $ won't hurt too much
