Advice on new system for Linux

[kramerjm-Re5JQEeQqe8AvxtiuMwx3w at public.gmane.org (James Kramer)]

My computer just died.  I had it for nearly 10 years.  I need to
purchase a new system and would like one that would last another 10
years.
1.  Would this system suite my needs.
2. I do not play games but I would like the option to upgrade in the future.
3.  I never used 64 bit Linux. I assume that by now most programs (ie
Firefox) are supported by it.
4. Do you think that I will run into any linux driver problems since
it is such a new system.
5.Can I dual boot with Win XP.  That is will WinXP run on a 64 bit.
It is my impression that AMD can simulate a 32 bit enviroment for
Windows.  Thanks you in advance for your suggenstions.
