I am not certain whether to have Vista 32 or 64 bit ..?

There are a few differences between the two types. x64 can run twice as many colours than x32, giving a much better looking image than you would be used to. Also, performance-wise, x64 is much faster than x32, and the difference is immediately noticable. Besides that, on an x32 system, the max amount of RAM that can be installed is 4GB, whereas on Vista Ultimate x64, you can have 128GB.

The main disadvantage of x64 (on XP mainly though) was that alot of programs still aren't compatible, deciding to stay with x32 for a little while longer. But seeing as Vista is primarily an x64 system, that problem won't be around much longer.

Hope that helps=]

Depends what you are going to use the computer for. For extensive gaming, go with the 64 bit. It is able to process more digits and the 32, and for gaming, this is what you want.

First: press on control panel.

Second: make sure you are viewing the control panel in classic view, if ur not press on the classic view option on the top left corner of the window.

Third: scroll down until you see the link that says "system" and click on it.

Lastly: under system type, it should tell you 32 bit or 64 bit.
