32 or 64 bit

so it there seems no reason not to buy it...

...first waiting for my BF3 to arrive, then to check if it does work with winXP - if not i'l buy it now, and not wait until i upgrade my system

It needs directx 10 or higher... so no XP.

Win 7 is excellent, and even vista was better than XP. So you are 2 generations behind.

x64 or 32bit...There is a tradeoff in that x64 uses more ram but also you can expand the ram by quite a lot.

There are hacks to get more ram in 32bit using PAE but it just isn't worth the effort considering there are so few downsides to x64

The reason for this concerns memory mapped IO and whats called an address space. An address space refers to all memory that the computer can access. It normally means main memory, except when memory mapped IO is involved (and it always is on modern computers). One quick note, programs have their own address space which is distinct to the windows address space. A program's address space is also smaller than the windows address space, since it must be able to fit into the windows address space. The biggest unsigned number that a 32 bit computer address is around 4 billion, which is why a 32 bit computer can access 4GB of memory, at maximum. However, this is not what Windows sees, and memory mapped IO is the reason. Memory mapped IO assigns a portion of that address space - which normally points to main memory - to your other devices, such as your sound card and your graphics card. This is convenient for programmers because it means we only have one address space to work with, but it means our 4GB address space has to be shared with both main memory and all devices. Obviously, since we need devices, main memory must shrink. This is why main memory becomes reduced in size.

These days, there is no reason to use 32 bit at all. You should never use it, even if only have 2GB of RAM right now. You'll just run into headaches when you eventually expand your memory. I've been using 64 bit windows since the Vista days, back in 2007, and never had any problems with it.

Thanks for the detailed response mate :)

yea, id stick to 32bit, 64bit just seems to give problems

Problems? What are these problems you speak of? :wtf:
I haven't had a single problem caused by having a 64-bit OS whatsoever.

I had to rebuild my PC in 64bit mode, as Adobe Premiere in CS5 only supports 64bit. Also, the other apps are also 64 bit.

I have had no problems with this build...

Go Windows 7 64x, will last you longer and give you more RAM space(if there is something like that)

64bit all the way! Got 12gb of RAM to prove it :P

You need to remember that the 64bit does not ONLY give you the ability to have more memory, but it also has a higher amount of registers to do , well, everything else. Exactly double, to be honest. So running 64bit software on 64bit os will perform better than it's 32 bit os and software on systems with the same amount of memory.

Think of it like 2 exactly similar GPUs, but having a 128bit vs 256bit memory architecture, we all know the 256 will have performance advantages.

well ordering my win7 64bit tomorrow...can't have my bf3 just sitting on my pc stand and gathering dust
