I make a very intensive use of my pc (I work from home), and I am planning on buying a new laptop. I currently have 2 centrino 2 (one is duo), one with XP and the other with vista home premium 32. I need very high performance (especially memory as I run a lot of tasks at the same time). I am not an IT expert and would like to know if Windows vista 64 is the best os available now and if it's worth istalling xp as well for compatibility with some older applications.
My questions are:
Can vista 64 exploit 4GM ram or even 6?
Are all application compatible with windows 64 also compatible with Vista 64.
Is there any difference in term of performance between home premium and business.
the laptop I would like to buy has
Intel core 2 quad Q9000 (2.0 GHZ) 6MB L2 cache, 4GB DDR2 800 mhz 640 GB hard disk. Is this the best solution?

Price is not a real problem if it's worth the difference...

Thanks in advance!

Windows 7 should be released for sale shortly.
If it were me & I could possibly wait I wouldn't buy until Windows 7 is out.

Now to answer your questions [the best I can]

Vista 64 bit can use more then the 4GB of memory you want.

Not all programs/applications that work on 64 bit XP will work on 64 bit Vista.
You need to check the software manufacturers web site to get the compatibility information.

"Is there any difference in term of performance between home premium and business."

I can't answer that one as I have never used the Business version.

Thanks for your answer! You speak about xp 64, but my question was actually if all which is compatible with vista 32 (which I have now and can test) will (normally) be compatible with vista 64.
Vista 32 cannot use more than 3GB of ram, isn't it?

32 bit OS's cannot use more than 3GB of ram while 64 bits can.
