Pent.D, should I use XP home or prof.?

[johnhenry]

My specs:
Intel Pentium D 3.0Ghz
2 GB Dual-channel RAM

I'm now running XP Home (SP2). Would I get any performance increases by switching to XP Professional?

I've heard only XP Pro. has support for 64 bit systems, but also, few programs now take advantage of this. And is dual core necessarily 64 bit?

Many, many thanks!

You won't get a performance increase by going with the Pro version, you won't get one with the 64-bit version either unless you intend to run memory heavy applications which benefit somewhat from 64-bit instructions & the extra memory addressability.
