Upgrading to Vista

[Eveready]

I am looking to upgrade my home system to the modern age. I am currently running Windows XP SP3 and do not have enough RAM to operate efficiently and I am also networked to another windows XP using a wireless adapter.
 If I upgrade to a new puter with Vista OS, will I run into any conflicts or problems that would warrant upgrading the mother unit?

... will I run into any conflicts or problems that would warrant upgrading the mother unit?

Uh..., what is the "mother unit"?

if your running XP and don't have enough RAM to operate efficiently, I doubt you'll even be able to install Vista, let alone run it well.

Thanks guys for your replies,
 Sorry, 1st let me re-innerate, I am planning on replacing my current puter with a new unit ( which of course most comes with Vista installed ), 2nd the (mother unit ) is also running XP and does have enough RAM to run efficiently.  I am looking to replace my unit with a faster system with at least 3 gigs of RAM.
       Once again,  Thanks for all of the help,,,,,,,,,  Eveready

OBTW,    The (Mother unit) is the wife's puter which I am networked to. I share printer and other accesssories via wireless adapter and router.  Again, Thanks

OK, you're getting a new computer with 3GB of RAM and the wife has a slow machine, one with insufficient memory.  For the sake of avoiding marital discord, why not do something to speed up wife's computer?

Sorry sir,, I thought that I had mentioned that her unit was newer unit and running efficiently,,   mine is the problem.   I just want to make sure that I do not have a conflict between the two operating systems.   Thanks

There will be no "conflicts" with the 2 computers if you home network contains a router.  You do have a router, don't you.

[Eveready]

Yes, we are using a wireless router, and your  kung fu is good, but I am using IE8

The choices are:
1.  Buy a new computer now with Vista.
2.  Buy a new computer now with Windows XP.
3.  Wait 3 months to buy a new computer with Windows 7.

IMHO, #1 is not an option.
