Then they haven’t tried Vista 64Bit then if they think that
I'm using Vista x64 myself, and while it is better than XP32 bit, so is the 32bit Vista install on my laptop. More to do with Vista than 64bit I think

Don't run them on the machine in spec matey, machine I use has 4gig installed and a Quadro FX. Its a system thats not overclocked however (which I'm really going to have to do), and that may wield some positive results.
In response to the original post... The Pentium D is so bad in its implementation of EM64T, that in general its faster and better to simply treat it as a 32bit processor and run 32bit windows.
Athlon64's and Core2 Duo's on the other hand were designed from outset to be high performance 64bit x64 processors and therefore run extremely well in both 32 and 64bit modes.
There is a lot of rubbish in this thread.. 32bit limited file formats.. What a load of... 80x86 is 64bit built ontop of 32bit ontop of 16 bit. You can still run MS-Dos 3.2 on the latest x86 processors if you really want to, and its not 'software' emulation its full hardware support.
In 16bit mode (virtually unused these days) applications have access to 8bit and 16 bit registers, 32bit mode adds 32bit registers, and 64bit mod adds 64bit registers.
In theory 64bit is the most flexible, as it can still access the original 8bit registers (AH/AL/BH/BL etc etc). But it can also be used in 'lazy' mode where even a some 1+1 = 2 calculation can be made using 64bit registers.
The two biggest advantages of 64bit mode are the ability to access more than 4gb of memory, and the ability to work on 64bit math without resorting to very complex code. However even that is 'somewhat' more limited than it may seem at first glance. That '64bit' math only applies to 'Integers' (whole numbers), as the 80x87 'co processor' was already capable of working with 32bit, 64bit and even 80bit extended 'floating point' math, and even 32bit and 64bit integer math. To make matters even more confusing MMX also supports 64bit integer maths, and SSE supports up to 128bit math.
Thats not to say that giving the main x86 processors the ability to work in 64bit natively is a bad thing, it adds futher flexbility to an already well featured instructionset, and the functions possible within the main processor are quite different to the pure math functions which can be made by the x87 maths extensions, or the MMX/SSE modules.

Kids.......Don't do Drugs ^^^^^^^^^^^^^
My pc runs a 32 bit windows xp OS
To my knowlage my processor is a 64 bit processor
If I installed a 64bit OS would my pc then run with the benafits of 64bit
Stick with 32b I have tried 64 and have used 4gb ram and to be honest I couldn't tell the difference and in benchmarks some were a lot worse on 64.
